Windows key not working is one of those faults that looks serious but often has a small reason. Either the key itself is being blocked by a lock mode, or the key is fine and the Start menu it should open is not responding. The first thing to find out is which of the two you have, because the fixes are completely different.
Press the key and watch. If nothing happens, even when you press Win + E to open File Explorer, then the key press is being blocked. If File Explorer opens but the Start menu will not show, then the key works and Windows has a Start problem. This page covers both cases, for Windows 10 and Windows 11, on laptops and desktops.
Common causes
1Windows key lock or Game Mode on the keyboard

What fixes itCheck the keyboard's own app, or ask your IT team
7Outdated or faulty keyboard driver

What fixes itRemove the keyboard entry in Device Manager, then reboot
How to fix it, step by step
Test the key with a simple shortcut
Press Win + E. If File Explorer opens, the key works and the Start menu is the problem, so skip to step five. If nothing opens, keep going from step two.
Release any lock on the key
Many gaming and some office keyboards have a switch that disables the Windows key so it is not pressed during a game. Look for a key with a Windows crossed out symbol, or try Fn + F6 or Fn + Windows key. Your keyboard's quick guide shows the exact one. Also check for a small slide switch on the keyboard body.
Restart the PC with the keyboard unplugged
For a desktop, unplug the USB keyboard, wait ten seconds and plug it into a different USB port. For a laptop, restart and test the key as soon as the desktop appears, before opening other programs.
Try a different keyboard
Connect any other USB keyboard. If its Windows key works, your own keyboard is at fault. If it fails too, the issue is inside Windows. This one test saves a lot of time.
Reload Windows Explorer
Open Task Manager with Ctrl + Shift + Esc, look for the Windows Explorer line, and use its Restart option. The screen blinks briefly. This revives a frozen Start menu in many cases. If the taskbar is also dead, see taskbar not working.
Check the keyboard helper options
Open Settings (click the gear in Start if the shortcut is dead) and look in the Accessibility section for the keyboard page. There, turn off the three helper options: Sticky, Filter and Toggle Keys.
Let Windows reload the keyboard driver
Use the right click menu on the Start button to reach Device Manager, find your keyboard under Keyboards and remove it. Reboot, and Windows detects the keyboard and installs the driver again.
Repair Windows files
From an administrator Command Prompt, enter
DISM /Online /Cleanup-Image /RestoreHealthfirst, thensfc /scannow, and reboot once both finish. Both tools ship with Windows.
Shortcuts you can use while the key is dead
| Normal shortcut | Another way |
|---|---|
| Win to open Start | Click the Start button, or press Ctrl + Esc |
| Win + E for File Explorer | Click the folder icon on the taskbar |
| Win + I for Settings | Start menu, then the gear |
| Win + D to show desktop | Click the thin strip at the far right of the taskbar |
| Win + Shift + S for screenshot | Use the search for the capture tool, or see Print Screen not working |
Windows key not working on a laptop: why it happens
On laptops the cause is often a function lock or a stuck Fn layer, because the key can share a position with another function. A laptop keyboard that was wet or dusty may have one key dead. If other keys also misbehave, read some keyboard keys not working, and for a full dead keyboard see laptop keyboard not working.
Do not pull keycaps off a laptop keyboard unless you know how that model clips on. The small hinges break easily and a new keyboard costs far more than the cleaning saves.
Office computers and disabled Windows keys
On a computer from work or college, administrators can switch off the Windows key through policy. If it stopped working after you joined a work account, ask the IT team before changing anything. Do not edit system settings you do not understand.
When to replace the keyboard
If the key is dead on a spare keyboard too, repair Windows. If it is dead only on yours and no lock mode helps, replacement is the answer. An external keyboard is a cheap stopgap for a desktop; a laptop needs a technician, and what you pay varies with the laptop model and how the keyboard is fixed in place.
Frequently asked questions
Why is my Windows key not working?
Common causes are a Windows key lock on the keyboard, Game Mode, Filter Keys, or a Start menu that has frozen. Test with Win + E to see which one applies.
How do I unlock the Windows key on my keyboard?
Look for the key with a crossed out Windows logo or try Fn with F6 or Fn with the Windows key. The exact combination depends on the keyboard maker, so check its guide.
Windows 11 Start menu will not open though the key works. Next step?
Reload Windows Explorer in Task Manager, install pending updates, and run the DISM and SFC repair commands. Restart afterwards.
Can a virus disable the Windows key?
It is possible but uncommon. Lock modes, settings and hardware wear are far more likely. If you suspect malware, run a scan with the built-in Windows Security.
My start button is not working on Windows 10 after an update. What now?
Restart the PC, restart Windows Explorer and check Windows Update for a newer fix. If it persists, repair system files with DISM and SFC.
