Windows & Multitasking Mastery — Handout

Read this before or alongside the hands-on practice. This is reading material only — the module itself is where you actually drag windows by their title bars, resize them from their edges, snap them to the sides of the screen, move things between programs with the clipboard and rescue a frozen program. 21 levels, 18 of them behind the module purchase.

The parts of a window

Title bar — the strip along the top carrying the program’s name. This is the handle you drag to move the window, and double-clicking it maximises.
Window controls — minimise (—), maximise (□) and close (✕), at the right-hand end of the title bar, in that order, in every program.
Borders and corners — the eight places you can grab to resize.
Content area — the program itself. This is the only part that differs from one program to the next, which is why learning the frame once is enough.

Minimise is not close

Minimise (—) hides the window. The program is still running, still holding your work, still using memory, and still listed in the taskbar. Close (✕) stops the program completely.

Clicking ✕ meaning “hide this” is the commonest accident on a computer. Going the other way, a machine that gets slower through the day is usually one where everything has been minimised and nothing has been closed.

Resizing — edges versus corners

Move the pointer onto a border and wait for it to become a double-headed arrow. If it is still a plain arrow, you are a pixel or two off, which is the usual reason a resize “does nothing”.

Edges (the top edge, the bottom edge, the right edge, the left edge) change one dimension.
Corners (the top-left corner, the top-right corner, the bottom-left corner, the bottom-right corner) change both at once, and anchor the opposite corner.

A window will not shrink below a minimum size. That is deliberate — below it the title bar could not fit its own buttons, and you would have a window you could no longer close.

Snapping — the fastest useful trick there is

Drag a window to the left or right edge → it fills that half of the screen.
Drag it into a corner → it fills that quarter.
Drag it to the top edge → it maximises.
Drag a maximised window’s title bar downwards → it comes back to its normal size.

A translucent preview shows exactly where the window will land before you let go. Two windows snapped left and right share a border down the middle: drag that border and both resize together, still filling the screen exactly.

A window that suddenly fills the screen while you were moving it has not broken — the pointer touched the top edge.

Several windows at once

Windows are stacked like sheets of paper — the Z-order. Whatever you click last is on top. Exactly one window is active (bright title bar), and it is the only one your keyboard talks to.

If you type and nothing appears, the window is almost certainly not focused — click it first. A window can be completely buried with no part showing; the taskbar lists everything open whether you can see it or not, and clicking its entry brings it forward.

Keyboard shortcuts

Windows takes the real combinations below before any program sees them — which is why they work from anywhere on your own machine, and why a web page can never receive them. The module substitutes the keys in the second column and behaves identically; use the real ones on a real computer.

On a real PC	In the module	What it does
Alt + Tab	Alt + Q	Open the switcher. Hold Alt and tap again to move along the list; release Alt to switch.
Win + D	Alt + D	Show the desktop — minimise everything. Press again to bring it all back.
Win + ←	Alt + ←	Snap the active window to the left half.
Win + →	Alt + →	Snap the active window to the right half.
Win + ↑	Alt + ↑	Maximise the active window.
Win + ↓	Alt + ↓	Restore a maximised window, or minimise a normal one.
Alt + F4	Alt + W	Close the active window.
Ctrl + C	Ctrl + C	Copy the selected item or text. Real, works as itself.
Ctrl + X	Ctrl + X	Cut the selected item. Real, works as itself.
Ctrl + V	Ctrl + V	Paste. Real, works as itself.
Ctrl + Shift + Esc	right-click the taskbar	Open Task Manager.

Every one of these acts on the active window. If a shortcut seems to do nothing, or acts on the wrong window, the active window was not the one you thought.

Virtual desktops

A second desktop is a second arrangement of windows on the same computer — not a second user account, not more secure, and not private. Create one in Task View, drag a window’s thumbnail onto it to move it there, and click a desktop tile to switch.

The taskbar lists only what is open on the desktop you are looking at, which is where beginners lose a window. Closing a desktop never closes its windows — they move to the desktop before it.

The clipboard — three rules

It holds one thing. A second copy replaces the first. Copying five files one after another and then pasting gives you the fifth, not five.
It only fills when you copy or cut. Pasting an empty clipboard does nothing and is not an error — go back and copy something first.
Cut does nothing until you paste. The file is only marked (and dimmed). An abandoned cut costs you nothing at all; the file never moved.

Copy (Ctrl+C) leaves the original and adds a duplicate — the file ends up in both places. Cut (Ctrl+X) moves it — it ends up in one. Paste is Ctrl+V, or the right-click menu; neither is more correct than the other.

The clipboard belongs to the whole computer, not to one program, so anything you can select you can copy: text on a web page, a figure in a spreadsheet, a line in an email, a file in a folder. Copying a long reference number is exact; retyping it is where transposed digits come from. The clipboard lives in memory, so it is emptied when the machine is switched off.

Settings — cosmetic versus functional

Personalisation (wallpaper, accent colour, light or dark) is purely cosmetic. Nothing there affects speed, files or safety, so nothing there can break anything. The accent colour does one useful job beyond taste: it marks the active window’s title bar, so a strong one makes focus easier to see.

Accessibility changes what a person can actually do. Text size enlarges writing across the whole system (not zoom, which magnifies one window) and is the single most valuable setting for anyone who holds a page at arm’s length. Pointer size cures losing the cursor on a big or bright screen. High contrast uses strong colours and hard edges — much easier to read with low vision or in daylight, and the usual explanation for a screen that has “suddenly gone strange”. The same switch turns it off.

Settings → About holds the processor, installed RAM, storage and operating system version. Memory and storage are different things and shops call both “memory” — always report both. What the numbers mean is taught in “Meet the Computer — Hardware Mastery”.

When something stops responding

First, look for a dialog. A modal dialog stops its program until you answer it, and it can be hidden behind another window. That is not a freeze.
In a “Save changes?” dialog: Save keeps the work and closes; Don’t save closes and discards; Cancel abandons the closing entirely and is the one people forget exists.
A real freeze shows “(Not Responding)” in the title bar. It is one program — the computer is fine.
Wait a minute first. A surprising number recover on their own.
Then Task Manager (Ctrl+Shift+Esc, or right-click the taskbar), select the program, End task. You lose unsaved work in that one program only.
Never hold the power button for one stuck program. That kills every program mid-write, and that is where lost work and damaged files actually come from.

Scope note

This module owns windows, the arrangement of them, and the clipboard. The taskbar as a subject — pinning programs, the Start menu, search, the clock and system tray, notifications, arranging desktop icons — belongs to “Computer, Mouse & Desktop Mastery”, which also teaches the click and drag gestures themselves. Creating, renaming, deleting and organising files and folders belongs to “Files & Folders Mastery”; copy, cut and paste are taught here because they are an operating-system mechanic that works between any two programs, not a file-manager feature. What the specifications in About This PC mean belongs to “Meet the Computer — Hardware Mastery”. None of these are omissions — each is another module’s territory, named so you know where to find it.

The Window Itself

Level 1 — What a Window Is

Window anatomy, the active window, and why focus decides where your typing goes.

A window is a program's frame on the screen — the box a program draws itself inside. Every program you run gets one, and everything you can do to a program's window, you can do to any program's window. That is the single most useful fact in this module: the frame is the same everywhere. Once you can move, size and arrange one window, you can do it to a word processor, a browser, a photo viewer or a program written twenty years from now.
One boundary before we start. The taskbar as a subject — pinning programs to it, the Start menu, search, the clock and system tray, notifications, arranging your desktop icons — is taught in a different module: “Computer, Mouse & Desktop Mastery”. You will see a taskbar here, but only doing one job: listing what is currently open, so you can switch between windows. Everything else about it belongs to that module, and it is not repeated here on purpose — you would be paying twice for the same lesson.
The labelled diagram beside the window names its parts. Read them once, then we will use every one of them. Title bar — the strip along the top carrying the program's name; this is the handle you drag. Window controls — the three buttons at the right of the title bar: minimise, maximise, close. Border and corners — the eight places you can grab to resize. Content area — the program itself, which is the ONE part that is different in every program.
Click the Notes window's title bar — the strip at the top with its name in it.
That window is now the ACTIVE window — the focused one. Its title bar is brightly coloured, and every other window's is dimmed. Focus matters more than it looks. Exactly one window receives what you type. If you start typing and nothing appears, nine times out of ten you are typing into a window that is not focused — click its title bar first.
Open the Web Browser by double-clicking its icon on the desktop.
Two windows now, and only one of them is focused — look at the title bars. The browser opened in front because the newest window goes on top. Windows are stacked like sheets of paper on a desk. That stack has an order, and clicking any window lifts it to the top of the pile. Level 6 goes into this properly.
Bring Notes back to the front by clicking it.

Level 2 — Moving a Window

Real title-bar dragging: put a window exactly where you want it.

A window sits wherever you leave it. To move one, you press and hold on its TITLE BAR, drag, and let go — the window follows the pointer the whole way. Everything in this level is a real drag: press the mouse button down, keep it down while you move, release where you want the window to land. If you are not confident with press-move-release itself, that gesture is taught from scratch in “Computer, Mouse & Desktop Mastery”.
Drag the Notes window by its title bar into the top-right area of the desktop.
Now drag it down to the bottom-left area.
Dragging the window's BODY does nothing to the window — it stays exactly where it is. That is not a fault. Inside the content area, dragging belongs to the program: in a word processor it selects text, in a photo viewer it might pan the picture. Only the title bar moves the window. Try it if you like — grab the white area and pull; the window will not follow.
Move the window back to the middle of the screen.
One thing you cannot do here, deliberately: drag a window so far off the screen that you cannot reach its title bar any more. On a real computer you can, and it is a classic beginner panic — the window is still open, still in the taskbar, but there is no title bar left to grab. The cure is a keyboard shortcut, or right-clicking the taskbar button and choosing Move. This simulation keeps the title bar reachable so you can practise without trapping yourself.
Open the Calculator, so there are two windows to arrange.

Level 3 — Resizing a Window

All eight handles: edges change one dimension, corners change both.

A window has eight places you can grab to resize it: four borders and four corners. An EDGE changes one dimension. A CORNER changes both at once. Move the pointer slowly onto a window's edge and watch the pointer change shape — a double-headed arrow means “you can drag here”. That change is the computer telling you the grab will work. If the pointer is still a plain arrow, you are a pixel or two off the edge, which is the single most common reason a beginner's resize “does nothing”.
Drag the RIGHT edge of the Notes window to the right, to make it wider.
Only the width changed. The height is exactly what it was. That is what an edge does, and it is why edges matter: when a window is the right height but too narrow, you want to fix the width and nothing else.
Now drag the BOTTOM edge downwards, to make the window taller.
Now drag the BOTTOM-RIGHT CORNER. Watch both the width and the height change together.
The corner is the one most people use, because it keeps the top-left of the window still while you size it. The other corners work the same way but anchor a different point: dragging the TOP-left corner keeps the bottom-right still, so the window grows upwards and to the left. Choose the handle by which part of the window you want to stay where it is.
Drag the LEFT edge to the left. Notice the window's right-hand side does not move — only the left side comes out.
Now make the window SMALLER: drag the bottom-right corner up and to the left.
A window will not shrink below a minimum size, and that is deliberate on real computers too. Below a certain size the title bar could not fit its own buttons, and you would have a window you could no longer close. If a window refuses to get smaller, you have reached its minimum, not found a fault.

Controlling a Window

Level 4 — Minimise, Maximise, Restore & Close (paid level)

The three title-bar buttons, the double-click shortcut, and why minimise is not close.

Three buttons sit at the right-hand end of every title bar: minimise (—), maximise (□) and close (✕). They are in that order, in that place, in every program. They are also the three buttons beginners confuse most often, and confusing them costs real work. This level makes the difference between them permanent.
Click the minimise button (—) on the Notes window.
The window is gone from the screen — but Notes is still RUNNING. Look at the taskbar: it is still listed there. Minimise means “get out of my way”. The program is still open, still holding your work, still using memory. Nothing has been closed and nothing has been saved or lost.
Bring it back: click its entry in the taskbar at the bottom.
Click the maximise button (□). The window fills the whole screen.
Maximised means the window is as large as the screen allows — right up to the taskbar, which stays visible. That is different from FULL SCREEN, which some programs offer separately (often with the F11 key) and which hides the taskbar and the title bar too. Maximised is the everyday one: the most room for your work while everything else is still reachable.
Click the same button again (it now shows ❐) to put the window back to its previous size.
Notice the window went back exactly where it was, at the size it was. A window remembers its “restored” position while it is maximised. That is why maximising to read something and then restoring is safe — you do not lose your careful arrangement.
There is a shortcut: DOUBLE-CLICK the title bar to maximise. Try it.
Double-click the title bar again to restore it.
Now close Notes with the ✕ button.
Closed is different from minimised in the one way that matters: the program has STOPPED. It is gone from the taskbar, it is using no memory, and anything unsaved was either saved, discarded, or you were asked about it first. The commonest beginner accident on a computer is clicking ✕ meaning “hide this”. The cure is not care — it is knowing which button is which, which you now do. And when a program has unsaved work, it will stop and ask before closing; that dialog is Level 18.

Level 5 — Snap Layouts (paid level)

Drag to an edge for a half, a corner for a quarter, the top to maximise — and resize a snapped pair together.

Snapping is the fastest useful thing in this entire module. Drag a window until the pointer touches the LEFT edge of the screen, and the window snaps to fill exactly the left half. You do not need to size it or line it up. While you are dragging near an edge, a translucent preview appears showing exactly where the window will land if you let go now. Release inside the preview and the window takes that shape.
Drag the Notes window by its title bar all the way to the LEFT edge of the desktop, until the preview appears, then release.
Now drag the Web Browser to the RIGHT edge, so the two windows sit side by side.
That is a snap group: two windows sharing the screen exactly, with no gap and no overlap. This is how anyone comparing two things works — a document beside the figures it is quoting, a form beside the paper it is being copied from, a video call beside notes. It takes two drags and needs no measuring.
The two windows share a border down the middle. Drag that shared border to the LEFT, to give the browser more room and Notes less.
Both windows resized at once, and they still fill the screen exactly. That is the part people miss: a snapped pair is resized together, not one at a time. If you resized them separately you would get a gap or an overlap. The shared border keeps them exact.
Drag the Notes window to the TOP edge of the screen. The top edge does not give you a half — it maximises.
That is worth knowing precisely because it happens by accident. A window that suddenly fills the screen while you were moving it did not break — you touched the top edge. To undo it, drag the title bar back downwards: a maximised window dragged down restores to its normal size and follows the pointer.
Drag the maximised Notes window's title bar downwards to un-maximise it.
The four CORNERS of the screen snap a window to a quarter. Four windows, four corners, and the whole screen is used with nothing overlapping. Quarter-snapping is what you want when you are watching several things at once — a dashboard, a report, a chat and a browser. On a small screen it is cramped; on a large one it is the most productive arrangement there is.
Drag Notes into the TOP-LEFT corner of the desktop so it snaps to a quarter.
Now drag the Web Browser into the BOTTOM-RIGHT corner.

Level 6 — Several Windows at Once (paid level)

Stacking order, focus, buried windows, and the taskbar as the list of what is open.

Real work is never one window. This level is about having several open at once and staying in control of them. Windows are stacked in an order — the Z-ORDER, as if they were sheets of paper on a desk. Whatever you click last is on top. The one on top with the bright title bar is the ACTIVE window, and it is the one your keyboard talks to.
Four windows are open and overlapping. Bring PHOTOS to the front by clicking on it.
Now bring NOTES to the front.
A window can be completely buried, with no part of it showing at all. It is not lost and it has not closed — you simply cannot click what you cannot see. That is exactly what the taskbar is for here: it lists everything open, whether you can see it or not. Click a window's taskbar button and it comes to the front even from the very bottom of the stack.
Bring the Calculator to the front using its TASKBAR button, not by clicking the window.
That is the only job the taskbar does in this module: it is the list of what is open, and clicking an entry brings that window forward. Everything else about the taskbar — pinning programs to it, the Start menu, search, the clock and system tray, notifications — is a subject of its own and is taught in “Computer, Mouse & Desktop Mastery”. It is left out here on purpose, not by oversight.
Arrange as well as stack: drag the Photos window to the top-right area so more of it is visible.
Minimise the Web Browser to get it out of the way without closing it.

Level 7 — Switching Between Windows (paid level)

The keyboard switcher with real hold-and-cycle, and clearing the screen in one keystroke.

Clicking is not the fastest way to change windows. Every operating system has a keyboard switcher: hold one key, tap another, and a small panel appears showing every open window so you can pick one. On a real Windows computer that is ALT + TAB: hold Alt, tap Tab to step along the list, release Alt to land on your choice.
Alt+Tab cannot be practised inside a web page, and this module will not pretend otherwise. Windows itself takes Alt+Tab before ANY program sees it — which is exactly why it works from anywhere, and exactly why this page can never receive it. So here the switcher opens on ALT + Q instead. Everything else is identical: hold Alt, tap Q to move along the list, release Alt to switch. Practise the behaviour here — the holding, the cycling, the releasing — and use Alt+Tab on your own machine, where it does the same thing.
Hold Alt and tap Q. The switcher opens. Keep holding Alt, tap Q again until the WEB BROWSER is highlighted, then release Alt.
The switcher does not list windows in the order you opened them — it lists them in the order you last USED them, most recent first. That is why a single quick Alt+Tab flips you back to the last window you were in. Two programs you are working between are always right next to each other in that list, no matter how much else is open. It is the single most useful keyboard habit on a computer.
Do it again: hold Alt, tap Q, and land on PHOTOS.
The other switching move is the opposite: hide everything at once and look at the bare desktop. On a real machine that is WIN + D; here it is ALT + D. It minimises every window in one keystroke, and pressing it again brings them all back exactly as they were. Two real uses: reaching something on the desktop without closing anything, and clearing the screen instantly when someone walks up to it.
Press Alt + D to show the desktop.
Press Alt + D again to bring every window back.

Level 8 — Keyboard Shortcuts for Windows (paid level)

Snap, maximise, restore, minimise and close without touching the mouse.

Everything you have done with the mouse so far can be done from the keyboard, and once your hands are on the keys it is far quicker. The reference card beside the desktop lists every shortcut in this module: what it really is on a Windows computer, what it is here, and what it does. On a real machine, the Windows key (the one with the Windows logo, between Ctrl and Alt) is the window-management key.
As with Alt+Tab: Windows takes every Win+key combination before any program sees it, so this page cannot receive them. Throughout this module ALT stands in for the Windows key. Alt+← here is Win+← there. Alt+↑ here is Win+↑ there. The behaviour is identical; only the key you press differs, and only because a web page is not allowed the real one.
Press Alt + ← to snap the active window to the left half of the screen.
Click the Web Browser to make it active, then press Alt + → to snap it to the right half.
That is the rule for every one of these shortcuts: they act on the ACTIVE window and nothing else. If a shortcut seems to do nothing, or does something to the wrong window, the active window was not the one you thought. Click the window you mean first — it costs one click and saves the confusion.
Press Alt + ↑ to maximise the active window.
Press Alt + ↓ to bring it back down from maximised.
Press Alt + ↓ again. From a normal-sized window, the same shortcut minimises it.
Bring it back from the taskbar.
The last one is the most dangerous and the most useful: ALT + F4 closes the active window. Here it is ALT + W. It is the fastest way to close something — and the fastest way to close something by accident, because it acts instantly on whatever is active. If the program has unsaved work it will still stop and ask you first, which is the safety net.
Click Notes to make it active, then press Alt + W to close it.

Organising Your Work

Level 9 — Virtual Desktops (paid level)

A second desktop for a second kind of work: create, move windows across, switch, close.

A virtual desktop is a second screen that does not exist. Same computer, same programs, same files — a second arrangement of windows you can flip to. It is not a second user account and it is not a second computer. Nothing is hidden from anyone and nothing is more secure. It is a way of putting a whole set of windows aside without minimising or closing any of them.
The reason people use them is that minimising ten windows and bringing back the right ten is exhausting. A teacher keeps lesson materials on Desktop 1 and marking on Desktop 2. An accountant keeps this month on Desktop 1 and last month's audit on Desktop 2. Somebody with a personal errand keeps work on Desktop 1 and the errand on Desktop 2, and switches when a colleague walks past. One keystroke, whole context changed.
Click the Task View button in the taskbar (the two-rectangles icon) and then click “+ New desktop” to create Desktop 2.
There are two desktops now, listed in Task View. Desktop 1 still has both your windows; Desktop 2 is empty. Creating a desktop opens nothing and closes nothing. It just gives you another empty surface.
Switch to Desktop 2.
Desktop 2 is bare — and look at the taskbar: it is empty too. The taskbar lists what is open on the desktop you are LOOKING at. This is exactly where beginners lose a window. It is not closed, it is not minimised, it is on a desktop you are not currently on. If a window has genuinely vanished, open Task View and look at the other desktops before assuming anything is wrong.
Switch back to Desktop 1.
Now move a window across: in Task View, drag the Web Browser's tile onto Desktop 2.
The browser is on Desktop 2 now and has gone from Desktop 1's taskbar. It never closed and never reloaded — the same window, on a different surface. That is the whole mechanic: create a desktop, put windows on it, flip between them.
Switch to Desktop 2 and confirm the browser is there.
Close Desktop 2 using the ✕ on its tile in Task View.
Closing a desktop does NOT close the windows on it. They move to the desktop before it — the browser is back on Desktop 1. That safety is deliberate on real systems too. Removing an arrangement should never destroy work. The only thing you lose is the arrangement itself.

Level 10 — Arranging a Real Workspace (paid level)

Real jobs, your choice of technique — side-by-side comparison, presenting, and four-up.

This level has no new buttons. It gives you real jobs and lets you choose the technique — which is what actually being competent looks like. Each task states an outcome, not a method. Snap it, drag it, use the keyboard, use Task View: if the arrangement is right, the task is right.
Task 1 — you are copying figures from the Budget Sheet into a report. Put the Budget Sheet on the LEFT half of the screen.
And put Notes on the RIGHT half, so you can see both at once.
The figures column is cramped. Give the Budget Sheet more of the screen by dragging the shared border.
That is the single most common professional window arrangement there is: source on one side, destination on the other, sized to suit what you are reading. Every person you have ever seen work quickly on a computer does this without thinking about it.
Task 2 — someone walks up to your desk while personal things are open. Clear the screen in one keystroke.
They have gone. Bring everything back exactly as it was.
Task 3 — you are about to present on a projector and want ONLY the browser visible, as large as possible. Maximise the Web Browser.
The presentation is over. Put the browser back to its normal size so you can see your other work again.
Task 4 — you need four things visible at once. Snap Notes into the top-left quarter.
Snap the Web Browser into the top-right quarter.
Snap Photos into the bottom-left quarter.
And the Calculator into the bottom-right quarter.

Moving Information

Level 11 — Copy & Paste (paid level)

The clipboard, Ctrl+C and Ctrl+V, the right-click menu, and why the original always stays.

The clipboard is a holding area belonging to the whole computer. You put something in it from one place and take it out somewhere else — a different folder, a different program, a different window entirely. It is the single most useful mechanic on a computer, and it is the same three commands everywhere: COPY (Ctrl+C), CUT (Ctrl+X), PASTE (Ctrl+V). Learn them once and they work in every program you will ever use.
Note the boundary: creating, renaming, deleting files and navigating folder trees are the subject of “Files & Folders Mastery”. Copy, cut and paste are taught HERE because they are not a file-manager feature — they are an operating-system mechanic that works between any two programs. Files just happen to be the clearest thing to practise on.
Two folder windows are open. Click Report.docx in My Documents to select it.
Now press Ctrl + C to copy it. Ctrl+C is real — this page genuinely receives it.
Nothing visible happened, and that is normal. Copying is silent: a copy of the file is now waiting on the clipboard. This is the moment beginners lose confidence, press Ctrl+C four more times, and assume it failed. It did not. Copy never shows anything; the proof comes when you paste.
Click inside the Photos window to make it active, then press Ctrl + V to paste.
Report.docx is now in BOTH windows. That is what copy means: the original stays exactly where it was, and a duplicate appears at the destination. Two separate files now exist. Changing one does not change the other. That matters — a copy is a snapshot, not a link.
There is a mouse route too. RIGHT-CLICK Sunset.jpg in Photos and choose Copy.
Right-click on the empty space inside My Documents and choose Paste.
Keyboard and menu do exactly the same thing. Neither is more correct. The menu is easier to learn because you can read the words. The keyboard is far quicker once your hands know it. Most people use the menu until the shortcuts stick, and then never go back.

Level 12 — Cut & Paste (paid level)

Moving rather than duplicating — and the fact that nothing moves until you paste.

CUT (Ctrl+X) looks like copy but means something different: MOVE this, rather than duplicate it. The crucial detail, and the one almost nobody is told: cutting does not move anything. It marks the file and makes a promise. Nothing actually moves until you PASTE.
Downloads is full of files that belong elsewhere. Select Invoice.pdf in Downloads and press Ctrl + X to cut it.
Look carefully: Invoice.pdf is STILL in Downloads — just dimmed. That dimming is the promise. It has not moved and it has not been deleted. If you walked away now, nothing would have changed. That is a genuine safety feature: a cut you never finish costs you nothing.
Click into My Documents and press Ctrl + V to complete the move.
NOW it moved. It is gone from Downloads and present in My Documents — one file, in one place, which is exactly what a move means. Compare with the previous level: after a copy the file was in both places; after a cut it is in only one. That is the entire difference, and it is the difference between tidying up and accidentally duplicating everything.
The menu route: right-click Receipt.pdf in Downloads and choose Cut.
Right-click the empty space in My Documents and choose Paste.

Level 13 — Copying Text Between Programs (paid level)

Select real text in one window and paste it into a completely different program.

The clipboard is not only for files. It carries TEXT between programs — and this is where it saves the most time and the most mistakes. Retyping a phone number, an address, a reference number or a figure is slow and it is where errors come from. Copying it is instant and cannot mistype.
In the browser window, select the phone number “+256 414 259 000” by dragging across it with the mouse.
Click into the Notes window and press Ctrl + V to paste the number.
That text went from a web page into a completely different program. The clipboard belongs to the COMPUTER, not to any one program. Anything you can select, you can copy — text on a web page, a figure in a spreadsheet, a line in an email, a file in a folder. And you can paste it anywhere that accepts that kind of thing.
Now copy the address “Plot 12, Kimathi Avenue, Kampala” from the browser.
Paste it into Notes.
One thing that catches everybody: pressing Ctrl+C with nothing selected copies nothing. The clipboard keeps whatever it had before, so pasting afterwards gives you the OLD thing and it looks as though copy is broken. Always check the text is actually highlighted before you copy.

Level 14 — Clipboard Rules & Mistakes (paid level)

One item at a time, paste-before-copy, and the abandoned cut — each made to fail on purpose.

Three rules govern the clipboard, and every clipboard mistake anyone makes is one of them being broken. Rule 1: it holds ONE thing. Rule 2: it only fills when you copy or cut — never on its own. Rule 3: cut does nothing until you paste. This level makes each rule fail on purpose so you recognise it when it happens for real.
Rule 2, demonstrated. The clipboard is empty. Click into the Notes window and press Ctrl + V.
Nothing happened, and nothing was going to. Pasting an empty clipboard is not an error — there was simply nothing to put down. This is behind the most common beginner sequence there is: press paste, see nothing, press it several more times, conclude the computer is broken. The fix is always the same — go back and copy something first.
Copy Report.docx.
Rule 1, demonstrated. Now copy Minutes.docx as well — WITHOUT pasting the first one.
Paste into the Photos window and see which one arrives.
Minutes.docx arrived — the second copy. Report.docx is gone from the clipboard entirely, because the clipboard holds one thing and the second copy replaced the first. So copying five files one after another and then pasting gives you the fifth, not five. To move several things at once you select them all first and copy once — selecting several items is taught in “Computer, Mouse & Desktop Mastery”.
Rule 3, demonstrated. Cut Sunset.jpg from Photos.
Now, without pasting, copy Family.png instead.
Sunset.jpg came back to normal. The cut was abandoned the instant something else went onto the clipboard, and the file never moved. That is the safety net in full: an unfinished cut costs nothing at all. It is also why “I cut it and now it is gone” is almost never true — the file is where it always was.

Making the Computer Yours

Level 15 — Personalising the Desktop (paid level)

Wallpaper, accent colour and light or dark — applied live, and completely harmless.

Everything about how a computer LOOKS can be changed, and none of it affects how the computer works. That is worth saying plainly, because beginners are often afraid to touch settings in case something breaks. Wallpaper, colours and light-or-dark are cosmetic. Nothing you do in this level can damage anything.
Open Settings from the desktop.
In the Personalisation pane, change the wallpaper to “Savannah”. Watch the desktop behind the window.
It changed immediately, with no “Apply” and no restart. The desktop behind the Settings window is genuinely different. That immediacy is the modern behaviour and it is a good thing: you can see what you are choosing while you choose it, and change your mind by clicking another one.
Change the accent colour to Green. Watch the title bars and the taskbar.
The accent colour is not just decoration — it is what marks the ACTIVE window's title bar, selected items, and buttons that are currently switched on. So it does one useful job beyond taste: it makes “which window am I typing into” easier to see at a glance. If you find focus hard to spot, a strong accent colour genuinely helps.
Switch the theme to Dark.
Dark mode inverts window backgrounds from light to dark. It is a preference, not an upgrade. It is easier on the eyes in a dim room and harder to read in bright sunlight; on some screens it saves a little battery. Choose what you can read comfortably — that is the only correct answer.
Switch back to Light.

Level 16 — Accessibility Settings (paid level)

Text size, pointer size and high contrast — settings that change what a person can actually do.

Accessibility settings are a different category from personalisation, and the difference matters: these ones change what a person can actually DO with the machine. A computer is not “correctly” set up in some absolute way. It is correctly set up when the person in front of it can read it and use it comfortably. Changing that is not a workaround — it is the machine doing its job.
Open Settings and go to the Accessibility pane.
Drag the text-size slider to 150%. Watch the text in every window get larger.
That is not zoom. Zoom magnifies one window; text size changes the size of writing across the whole system — menus, labels, titles, everything. For anyone who holds a page at arm's length to read it, this is the single most valuable setting on a computer. It is under-used mostly because people do not know it exists.
Bring it back to 125% — often the comfortable middle.
Now make the mouse pointer larger: set the pointer size to Large.
A bigger pointer solves a real, specific problem: losing the pointer on a large or bright screen and waving the mouse around to find it. It costs nothing and it is worth trying even if your eyesight is fine — in a well-lit room, on a projector, or on a big monitor, most people find it out of the way and easier to follow.
Turn High contrast ON.
High contrast throws away subtle colours and uses strong ones with hard edges — deliberately less pretty, and far easier to read for anyone with low vision or on a washed-out screen in strong daylight. It changes appearance drastically, which is exactly why people switch it on by accident and think something has broken. It has not: this same switch turns it off again.
Turn High contrast back off.

Level 17 — About This PC (paid level)

Where the processor, RAM, storage and system version live, and how to report them accurately.

Every computer can tell you what it is. The About pane in Settings lists the processor, how much memory is installed, how much storage there is, and which version of the operating system is running. You will be asked for these more often than you expect: by anyone helping you with a problem, by software that states a minimum requirement, and by yourself when deciding whether a machine can do a job.
Open Settings and go to the About pane.
Read the panel. Device name, processor, installed RAM, storage, system type, operating-system version. The one that surprises people is “Installed RAM”. RAM is memory, and memory is not storage — 8 GB of RAM and a 512 GB SSD are two completely different numbers describing two completely different things, and shops routinely call both “memory”.
What those numbers MEAN — how to judge whether a processor is fast, how much RAM is enough, HDD versus SSD, how to read a shop's specification and choose a machine — is a whole subject, and it is a different module. “Meet the Computer — Hardware Mastery” covers all of it in depth, including reading a real listing line by line and choosing a machine for a real customer. This level only teaches you where the numbers live and how to report them accurately. It is deliberately short.

When Things Go Wrong

Level 18 — Dialog Boxes (paid level)

Save / Don't save / Cancel, what modal means, and the hidden dialog that looks like a freeze.

A DIALOG BOX is a small window a program puts up when it needs an answer before it can go on. “Save changes?”, “Are you sure?”, “Choose a file”. Most of them are MODAL, which means the program stops until you answer. That single fact explains a very common false alarm: a program that appears frozen is often just waiting for a dialog you have not noticed.
Notes has unsaved work and you tried to close it. A dialog is asking what to do. Choose “Save”.
That dialog had three buttons and each does something genuinely different. Save keeps the work and closes. Don't save closes and throws the changes away. Cancel abandons the closing entirely and leaves you where you were. Cancel is the one people forget exists. If you clicked close by accident, Cancel undoes the accident completely — you do not have to choose between saving and losing.
Here is the false alarm. Notes is not responding to clicks — because a modal dialog is waiting behind the browser window. Bring Notes to the front to find it.
There it is. Answer it with “Don't save”.
Nothing was wrong with the program. It was doing exactly what it was designed to do: waiting for an answer. So before deciding anything is frozen, look for a dialog. Bring the window to the front, check behind other windows, check the taskbar for a second entry from the same program. A genuine freeze is Level 19 and it looks different.

Level 19 — When a Window Freezes (paid level)

“Not Responding”, waiting, Task Manager, End task — and why the power button is the wrong answer.

Sometimes one program genuinely stops. The window stops redrawing, clicks do nothing, and after a few seconds the title bar adds the words “(Not Responding)” and the window may go pale. The most important fact about this: it is ONE program. The rest of the computer is fine, your other windows are fine, and nothing has been lost yet. Holding the power button — which is what most people do — turns one stuck program into every program being killed mid-write, and that is how work actually gets lost.
The Web Browser has frozen. Click inside it and see for yourself that it does not respond.
Before doing anything drastic: WAIT. Thirty seconds to a minute. A surprising number of “frozen” programs are simply busy with something large and come back on their own. Notice too that Notes beside it still works perfectly. That is the proof the computer is healthy. If everything were frozen you would have a different problem — and even then, a proper restart beats holding the power button.
It has not come back. Open Task Manager: RIGHT-CLICK an empty part of the taskbar and choose “Task Manager”.
On a real computer, Ctrl+Shift+Esc opens Task Manager directly, and Ctrl+Alt+Del gives you a menu containing it. Neither can be practised in a web page — Windows takes both before any program sees them, exactly like Alt+Tab. The taskbar right-click route used here is a genuine route that works on a real machine too, so what you are practising is real.
Task Manager lists every running program with its status. The Web Browser shows “Not Responding”; everything else says “Running”. That list is the answer to “is it the program or the computer?”. One “Not Responding” among a page of “Running” is one stuck program — and now you know precisely which one.
Select the Web Browser in the list and click “End task”.
The frozen window is gone and everything else carried on untouched. That is the correct outcome. Be honest about the cost: End task kills the program immediately, so anything unsaved in THAT program is lost. It is a last resort after waiting — but it is a far smaller loss than restarting the whole machine, which loses the unsaved work in every program at once.

Putting It All Together

Level 20 — Comprehensive Practical Exam (paid level)

Twenty single-attempt tasks drawn from every level in the module.

Twenty tasks drawn from every level in this module. Each is a single attempt and each counts. The pass mark is 15 out of 20. If you do not reach it, every level is still there to practise — free practice is unlimited, and the exam can be retaken as many times as you like.

Level 21 — Capstone: A Full Working Session (paid level)

One continuous morning's work — arrange, copy, move, separate, clear, and close down properly.

One continuous working session, start to finish. No new techniques — this is everything in the module used the way it is actually used, in the order a real morning happens. Nothing here is single-attempt. Take as long as you like and use whichever method you prefer for each step; the outcome is what is graded.
You arrive and open your morning's work. Open the Web Browser.
You are copying figures from the Budget Sheet into an email. Snap the Budget Sheet to the left half.
Snap Mail to the right half, so both are visible.
The figures column is too narrow. Drag the shared border to give the Budget Sheet more room.
Copy the total “UGX 1,450,000” from the Budget Sheet.
Paste it into the Mail window.
Downloads has an invoice that belongs with your documents. Open Downloads.
Open My Documents too.
Cut Invoice.pdf from Downloads.
Paste it into My Documents to complete the move.
A personal errand comes up and you do not want it mixed into your work. Create a second desktop for it.
Move the Web Browser to Desktop 2, out of your working desktop.
Switch to Desktop 2 to deal with the errand.
Done. Switch back to Desktop 1 and your work exactly as you left it.
Someone is coming to your desk. Clear the screen in one keystroke without closing anything.
They have gone. Bring everything back.
The end of the session: tidy up. Close the Mail window with the keyboard.
And close the Budget Sheet.
That was a whole working session managed deliberately: windows arranged on purpose, information moved between programs without retyping a character, personal work kept separate, the screen cleared in a keystroke, and everything closed properly at the end. None of it was fast the first time and all of it becomes automatic. That is what competence with a computer actually looks like — not knowing more programs, but running the ones you have without friction.
