To stop the Windows key from opening Start while you play, check your keyboard’s Win Lock or Game Mode control first. Its shortcut depends on the keyboard model. There is no universal Fn combination that works on every PC.
A Windows-key lock is different from locking your computer. Windows + L locks the Windows session; a keyboard’s Win Lock blocks the key or selected shortcuts.

Choose the right way to lock the Windows key
| Method | Useful for | Main limit |
|---|---|---|
| Keyboard Win Lock or Game Mode | A quick gaming toggle. | Keys blocked and shortcuts vary by model. |
| Keyboard maker’s app | A supported keyboard with configurable game settings. | May need the maker’s software or a saved device profile. |
| PowerToys Keyboard Manager | Reversible remapping during normal desktop use. | Must be running; not a dependable solution for every game. |
| Windows + L | Locking your computer when you step away. | Does not disable the Windows key. |
Check the keyboard’s own lock
- Look for a Win Lock label, a Windows-key symbol with a lock, or a Game Mode switch.
- Check the manual for your exact keyboard model before trying a key combination.
- Turn the lock on, then test the Windows key outside a game.
- Use the same documented control to turn it off again.
Some keyboards have a dedicated button; others use an Fn shortcut or a setting in the manufacturer’s app. A shortcut mentioned for another keyboard may change something else on yours.
Also check what Game Mode blocks. A keyboard may disable more than the Windows key, such as a menu key or selected shortcuts. A padlock light alone does not tell you exactly which keys are affected.
Remap the key with PowerToys for desktop use
Microsoft‘s PowerToys Keyboard Manager can remap keys and shortcuts. It offers a reversible alternative to changing the Windows registry.
- Install PowerToys from Microsoft’s official source and open its settings.
- Enable Keyboard Manager, then open Remap a key.
- Select the left or right Windows key you want to block.
- Choose the action that disables the selected key and save the mapping.
- If your keyboard has two Windows keys, handle each one you intend to disable.
Keep another way to reach Start, such as clicking its taskbar button. To undo a mapping, remove it, turn off Keyboard Manager or close PowerToys.
Microsoft warns that game input can behave differently and recommends avoiding Keyboard Manager while gaming because of possible performance effects. For that use, a keyboard’s own supported lock is the better starting point. The remapping also does not work on password screens where PowerToys is not running.
If the Windows key has stopped working by accident
- Turn off the keyboard’s Game Mode or Win Lock using its manual.
- Check the maker’s software for a remapped or disabled key.
- Check whether PowerToys or another remapping tool is running.
- Try the other Windows key or another keyboard, if available.
For broader layout and accessibility settings, see our Windows keyboard settings guide. If a shortcut unexpectedly changed the display or typing behavior, our accidental key-press guide covers common checks.
What changes when you disable the key?
Shortcuts that use the Windows key may stop working too. These include Windows + E for File Explorer, Windows + I for Settings and Windows + V for clipboard history.
If clipboard history will not open, restore the key before assuming the clipboard is broken. Our Windows 11 clipboard guide separates a shortcut problem from a history or sync problem.
Should I copy a registry file to disable it?
That is unnecessary for the reversible methods above. A registry keyboard mapping can affect more than you intended if the file is wrong. Use the keyboard’s documented control or a clearly visible remapping setting first.
