How to Fix Lightshot Not Working in Windows 11

If Lightshot isn’t working on Windows 11, you may notice that the shortcut key doesn’t respond, the app doesn’t open, screenshots aren’t saving, or nothing happens when you press the Print Screen button. In most cases, this issue is caused by shortcut conflicts, background app interference, outdated versions, or permission problems—not a serious system issue.

The good news is that Lightshot problems can usually be fixed quickly.

Windows 11 can override the Print Screen key.

Then try Lightshot again.

If it works, add Lightshot to your antivirus exclusion list.

7. Update Windows 11

System bugs can cause shortcut conflicts.

1. Open Settings > Windows Update.

4. Restart your PC.

Updates from Microsoft often improve keyboard shortcut and system compatibility.

This can resolve key mapping issues.

Wrapping Up

When Lightshot isn’t working on Windows 11, the issue is usually related to shortcut conflicts, background interference, or permission settings—not hardware problems. Disabling Windows’ built-in Print Screen override and reinstalling the app fix the issue in most cases.

Once resolved on Microsoft Windows, Lightshot should function normally again, allowing you to capture screenshots quickly and efficiently.
