Question

Widows11 update H25 won't install. I.ve tried 5 or 6 times. It gets to 100% and then says retry.

Answer 1

If you're experiencing issues with the Windows 11 update H25 not installing and it gets stuck at 100% with a retry message, there are a few steps you can take to troubleshoot the problem:

1. Check for Updates Again: Sometimes, simply checking for updates again can resolve the issue. Go to Settings > Windows Update and select Check for updates.
2. Restart Your Device: Restarting your device can help apply any pending updates or changes that may be causing the issue.
3. Use the Windows Update Troubleshooter: Windows has a built-in troubleshooter that can help identify and fix problems with Windows Update. You can find it in Settings > Update & Security > Troubleshoot > Additional troubleshooters > Windows Update.
4. Install Updates Manually: If the update continues to fail, consider downloading the update manually from the Microsoft Update Catalog and installing it.
5. Check Disk Space: Ensure that you have enough disk space available on your device, as insufficient space can prevent updates from installing.
6. Review Known Issues: Check if there are any known issues related to the update that might be affecting your installation. You can refer to the Windows release health status for updates on known issues.

If these steps do not resolve the issue, you may want to seek further assistance from Microsoft Support.
