Windows Logo+M is the keyboard shortcut to minimize all open windows and show the desktop. Windows Logo+D also shows the desktop but works differently (it toggles). Windows Logo+E opens Windows Explorer, and Windows Logo+U opens the Utility Manager. Logo+M is specifically for minimizing all windows.

Pressing the Windows key opens the Start Menu in Microsoft Windows operating systems. This is the primary and most direct way to access the Start Menu, which provides access to programs, settings, and files. The Esc key (option A) is typically used to cancel or go back, Alt (option B) is used as a modifier key in keyboard shortcuts, and Pause Break (option D) is rarely used in modern computing.

Pressing the Windows key + Pause/Break simultaneously is the keyboard shortcut to directly open the System Properties window in Windows. This provides quick access to system information, device manager, and Windows activation settings. Windows key + Ctrl (option A) is used for other purposes, Pause/Break alone (option C) doesn't open System Properties, and Windows key + Ctrl + Alt (option D) is not a standard Windows shortcut.

Pressing Windows key + R is the keyboard shortcut to open the Run dialog box in Windows, which allows you to quickly launch programs, open files, or access system features by typing commands. The other combinations are not correct - Windows key + @ (option A) and Windows key + Alt (option B) are not standard Run shortcuts, and Windows key + X (option D) opens the Quick Link menu instead.

Windows key + L is the universal keyboard shortcut to lock your workstation in Windows. This immediately takes you to the lock screen, requiring your password or PIN to sign back in. Options A (Settings), C (Search), and D (invalid shortcut) are incorrect for locking.

Windows key + F opens the search interface directly in Windows, allowing you to quickly search for files, apps, and settings. The other options are for different functions: Pause/Break shows System Properties, Tab shows Task View, and Alt+Del opens a security menu (not the standard Ctrl+Alt+Del).

Windows key + D minimizes all open windows to show the desktop. Pressing it again restores the windows to their previous state. This is a quick way to clear your screen or access desktop icons. Options R (Run dialog), M (minimize all, no restore), and Q (quick search) don't perform this toggle function.

Windows key + U opens the Utility Manager (Ease of Access Center) in Windows, which provides accessibility tools. Options M (minimize), R (Run dialog), and Ctrl+Alt+Del (security menu) don't open the Utility Manager.

Windows key + F1 opens Windows Help and Support, providing direct access to help articles and troubleshooting. The function key F1 is universally associated with 'Help' in computing. Options F5 (refresh), F2 (rename), and F8 (boot menu) have different functions.

Windows key + E is the standard keyboard shortcut to open Windows Explorer (now called File Explorer). Windows key + F opens search, Windows key + R opens Run dialog.

Shift + Delete is the keyboard shortcut for permanently deleting files or folders without sending them to the Recycle Bin in Windows. This is useful when you want to quickly delete items you're certain you don't need. Ctrl + D typically has different functions depending on the application (like bookmarking in browsers).

Ctrl + Alt + Delete is the universal Windows keyboard shortcut to open Task Manager or the security options screen. It brings up a menu where you can select Task Manager to view and manage running processes. This shortcut has been standard in Windows since the early days and works even when applications freeze.

Alt + Tab is the standard Windows keyboard shortcut for switching between open applications. This shortcut cycles through all active programs, allowing users to quickly toggle between them without using the mouse. Ctrl + Tab switches between tabs within an application, while Windows + Tab opens Task View.

Alt + Enter is the Windows keyboard shortcut to toggle between windowed and full-screen mode for the Command Prompt and many other applications. This shortcut quickly maximizes the Command Prompt window to full screen. Shift + Enter typically does nothing in this context, while Alt + E opens the Edit menu.
