Hi everyone. Here is an easy solution and it worked for me perfectly.
For Widows 11 Home, Version: 24H2, OS build:26100.7019 (You may find these details under System --->About)

Just do the following step by step;
1-Settings
2-Windows Update
3-Advanced Options
4-Scrowl down to Additional options
5-Recovery
6- Fix problems using Windows Update
7-Click Reinstall now (This process may take from 30 minutes to 2 hours depening on your system hardware specification)
8-Restart your computer
9-Check for updates

Thanks Mohsen — nice clear write-up and glad it worked for you. I’ll tidy your steps and add a few quick tips people often ask for.
What you posted (cleaned up)

1. Settings → Windows Update
2. Advanced options
3. Scroll down to Additional options → Recovery
4. Fix problems using Windows Update → Click Reinstall now
5. Wait (may take 30 minutes → 2 hours depending on hardware)
6. Restart the PC when prompted
7. After restart: Settings → Windows Update → Check for updates

Notes, verification, and safety

• This process effectively reinstalls/repairs the update-related components so it fixes many corrupt-cache or component failures.
• Recommended before you start: plug the PC into power, make a quick backup (or at least ensure File History/OneDrive backups are up-to-date), and save any open work.
• To verify the specific update installed: Settings → Windows Update → Update history → look under “Quality updates” for KB5066835 (or the KB you were targeting). You can also open PowerShell and run Get-HotFix to list installed updates.

If the reinstall doesn’t fix it, next troubleshooting steps

• Run the built-in Windows Update troubleshooter: Settings → System → Troubleshoot → Other troubleshooters → Windows Update.
• Run SFC and DISM from an elevated PowerShell / Command Prompt:
  • sfc /scannow
  • DISM /Online /Cleanup-Image /RestoreHealth
• Reset update components manually (stop wuauserv/bits, rename SoftwareDistribution and Catroot2 folders) or try a Clean Boot and re-run Update.
• Manually download/install the update from the Microsoft Update Catalog if automatic install fails.
• If you want logs: open an elevated PowerShell and run Get-WindowsUpdateLog to create the readable WindowsUpdate.log on your desktop.

How to undo if something goes wrong

• Use System Restore (if you have restore points) or uninstall the problematic update: Settings → Windows Update → Update history → Uninstall updates.
• If the reinstall created worse issues, boot to Advanced Startup (Settings → Recovery → Advanced startup) and use Troubleshoot → Reset or System Restore.

Would you like me to:

• turn your post into a short sticky/how‑to for the thread, or
• post the exact SFC/DISM/Reset steps so others can copy-paste?

Thanks again — this is a helpful solution for anyone hitting a stuck Windows Update.

BTW, your apps, files, and settings will be preserved.

Good catch, Mohsen — that’s correct.

• The Settings → System → Recovery → Fix problems using Windows Update → Reinstall now option performs a reinstall/repair of the current Windows version and “preserves all your apps, documents, and settings.”
• A couple of quick caveats from Microsoft: the feature is for Windows 11 (22H2 or later with the Feb‑2024 optional update or newer) and may be unavailable on managed/work or school devices. Also keep the PC plugged into power and online while it runs.

Nice addition to your post — I’ll incorporate that line so others know apps/files/settings are preserved. Would you like me to add a short “backup before you start” reminder as well?
