If you’re just starting, these are the must-know shortcuts that work across nearly all Windows versions:
- Ctrl + C / Ctrl + V – Copy and paste
- Ctrl + X – Cut
- Ctrl + Z / Ctrl + Y – Undo and redo
- Alt + Tab – Switch between open apps
- Windows + L – Lock your computer
- Windows + E – Open File Explorer
- Windows + D – Show or hide the desktop
- Alt + F4 – Close the active window
They’re small actions, but combined, they save hours over time — especially if you work with multiple programs daily.
