Dear bettylylyb,
Thank you for your question and for sharing the details into Microsoft Q&A Forum.
I understand how frustrating it can be when a laptop keyboard becomes intermittent after upgrading to Windows 11 25H2, especially when it sometimes stops responding or produces unexpected characters. You may also want to review the AI suggested answer above, as it includes several practical steps that are worth trying. In addition, I’ve outlined a structured set of troubleshooting steps below to help narrow down the cause and improve the keyboard behavior.
- Check keyboard layout / input language
- If Windows switches to a different keyboard layout, you may see incorrect characters even though the hardware is fine.
- Go to Settings > Time & language > Language & region
- Select your primary language > Language options
- Under Keyboards, remove layouts you don’t use and keep only the correct one.
- Disable accessibility features that can affect keyboard behavior
- Features such as Filter Keys or Sticky Keys can make the keyboard feel delayed, unresponsive, or behave unexpectedly.
- Go to Settings > Accessibility > Keyboard
- Turn Off: Sticky Keys, Filter Keys, and Toggle Keys (if enabled).
- Repair Windows system files
- Open Command Prompt (Run as administrator)
- Run these commands (in order):
DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow
- Then Restart
- Perform a Clean Boot to identify software conflicts
- If a background service/app (keyboard hotkey utility, macro tool, overlay, etc.) is interfering, a Clean Boot can help confirm it.
- Follow Microsoft’s Clean Boot steps to start Windows with minimal non-Microsoft services and startup apps: How to perform a clean boot in Windows - Microsoft Support
If the keyboard works normally in Clean Boot, it suggests a third-party service/app may be contributing. You can then re-enable items gradually to pinpoint the specific one.
- If the issue started immediately after the upgrade: uninstall the latest update or use System Restore
- When a problem begins right after an update, rolling back the most recent quality update can be a practical troubleshooting step.
- Settings > Windows Update > Update history > Uninstall updates

I hope the steps above help stabilize your laptop keyboard and prevent the intermittent unresponsiveness or incorrect characters. Wishing you a smooth experience on Windows 11 25H2 and consistent typing performance going forward.
