Windows update install failures

Question

I have had several attempts to update Windows 11 end with "Install failed" which also failed. Solutions would be helpful

Answer 1

Hi Kay Byars,

I understand how inconvenient it can be to keep seeing Windows updates fail. Since the issue is still occurring, the next step I’d recommend is renaming software distribution folders. This process helps clear out corrupted or stuck update files so Windows can download fresh components and try the update again.

To do this, please open Command Prompt as administrator, then run the following commands one by one:

net stop bits
net stop wuauserv
ren %systemroot%\softwaredistribution softwaredistribution.bak
ren %systemroot%\system32\catroot2 catroot2.bak
net start bits
net start wuauserv

Once completed, restart the device, then go to Settings > Windows Update and check for updates again.

If the update still doesn’t install after this, the next recommended option would be an in‑place upgrade (repair install). This refreshes Windows system files using the latest version while keeping your personal files and apps intact, and it’s often effective when standard troubleshooting doesn’t resolve update issues.

*Disclaimer: Let’s try performing an in-place install or in-place upgrade which will refresh your Windows files and operating system without removing files or applications. That being said, we always recommend that if you have important data, you should back it up before making large system changes. If you want to back up your data first, please do so. Once you are done backing up, you can follow the steps in the following guides: How to run In-place upgrade in Windows 11 - Microsoft Q&A 

I hope this helps move things forward. Please feel free to let me know how it goes or if you’d like guidance with any steps. I’m happy to help further.

Follow these steps in order to diagnose and fix repeated Windows 11 update install failures:

1. Run the Windows Update troubleshooter (Windows 11)
   • Open the Get Help app using the link in the Windows Update troubleshooter article: Run the troubleshooter in Get Help.
   • Let it automatically run diagnostics and apply any fixes.
   • If it cannot resolve the issue, continue with the next steps.
2. Check the exact error code for the failed updates
   Error messages like “Install failed” are generic. To see what is actually going wrong:
   • Select Start > Settings > Windows Update > Update history.
   • Find the update(s) that show Failed and note the error code (for example, 0x80070070, 0x80073712, 0x800f0922, etc.).
   • Different codes have different fixes; if needed, use that code with the guidance in the Windows upgrade/installation errors article or contact Microsoft support from there.
3. Apply general fixes for upgrade/install errors
   From the Windows 11 upgrade/installation guidance:
   • Remove external hardware: Unplug nonessential USB devices (external drives, printers, scanners, docks, etc.).
   • Update Windows and drivers first: Make sure all important updates and hardware drivers are already installed before attempting the problematic update again.
   • Uninstall non‑Microsoft antivirus: Temporarily remove third‑party antivirus (rely on Microsoft Defender during troubleshooting).
   • Uninstall nonessential/old software: Remove outdated or unnecessary programs that might interfere with setup.
4. Fix possible component corruption with DISM and SFC
   If updates repeatedly fail, system files or the Windows Update component store may be corrupted:
   1. Open Command Prompt as administrator (Start → type Command Prompt → right‑click → Run as administrator).
   2. Run DISM to repair the component store:

            DISM.exe /Online /Cleanup-image /Restorehealth
      

      Wait for it to complete (this can take several minutes).
   3. Then run System File Checker:

            sfc /scannow
      

   4. When both finish, close Command Prompt and run Windows Update again.
5. Handle specific common error codes (if seen)
   After checking Update history:
   • 0x80070070 – 0x50011 / 0x50012 / 0x60000: Not enough disk space. Free space on the system drive, then retry.
   • 0x80073712: A required file is damaged or missing. The DISM command above is the recommended fix.
   • 0xc1900223: Problem downloading/installing the selected update; Windows Update will retry automatically.
   • 0xC1900208 – 0x4000C: Incompatible app blocking the upgrade. Uninstall the incompatible app and retry.
   • 0xC1900107: Previous installation cleanup pending. Restart the device; if that does not help, run Disk Cleanup and clean temporary and system files, then retry.
6. If updates still fail
   • Use the detailed Windows Update troubleshooting steps under General troubleshooting in the Windows update problems article (after backing up important files as recommended).
   • If failures continue and you have a specific error code, use the “Get help with Windows upgrade and installation errors” article’s error table for targeted steps, or contact Microsoft support from that page with the error code and Update history details.
