Solution Steps

  1. 1 Run the Windows Update Troubleshooter. Press Win+I to open Settings, go to System → Troubleshoot → Other troubleshooters, and click 'Run' next to 'Windows Update'. This tool automatically detects and fixes common update issues, including corrupted cache.
  2. 2 Stop the Windows Update service and delete the SoftwareDistribution folder. Press Win+R, type 'services.msc', and press Enter. Find 'Windows Update' in the list, right-click it, and select 'Stop'. Then open File Explorer (Win+E), navigate to C:\Windows\SoftwareDistribution, and delete all its contents. This folder stores temporary update files, and clearing it forces Windows to download them fresh.
  3. 3 Rename the Catroot2 folder. In the same services window, also stop 'Cryptographic Services'. Then in File Explorer, go to C:\Windows\System32, find the 'Catroot2' folder, and rename it to 'Catroot2.old'. This folder stores update signatures, and renaming it forces Windows to recreate it.
  4. 4 Run the System File Checker (SFC) and DISM. Open Command Prompt as administrator (Win+R, type 'cmd', press Ctrl+Shift+Enter). Run 'sfc /scannow' and wait for it to complete. Then run 'DISM /Online /Cleanup-Image /RestoreHealth'. These tools scan and repair corrupted system files that might be causing the update error.
  5. 5 Restart your PC and try Windows Update again. Press Win+I → Windows Update → Check for updates. If the error persists, you may need to use the Windows Update Assistant or Media Creation Tool to perform an in-place upgrade repair.
  6. 6 If all else fails, perform a repair upgrade using the Windows 11 ISO. Download the Media Creation Tool from Microsoft's website, run it, and choose 'Upgrade this PC now'. This reinstalls Windows while keeping your files and apps, which can fix deep-seated update issues.

  1. Press Windows key + R to open the Run dialog. Type 'services.msc' and press Enter. This opens the Services window where you can control background Windows services. We'll stop the Windows Update service so we can safely delete its temporary files.
  2. In the Services list, scroll down to 'Windows Update'. Right-click it and select 'Stop'. If it's already stopped, that's fine. This halts the update process so no files are in use.
  3. Press Windows key + R again, type 'cmd', and press Ctrl+Shift+Enter to open Command Prompt as administrator. Click 'Yes' if prompted. This gives you the power to run system commands.
  4. In the Command Prompt, type the following command and press Enter: 'net stop wuauserv'. This is another way to stop the Windows Update service, ensuring it's fully stopped.
  5. Now, press Windows key + R, type 'C:\Windows\SoftwareDistribution', and press Enter. This opens the folder where Windows stores downloaded updates. Select all files inside (Ctrl+A) and delete them. If some files are in use, skip them — they'll be handled later. This clears out any corrupted update files.
  6. Go back to the Services window, right-click 'Windows Update', and select 'Start'. This restarts the service with a clean slate.
  7. Finally, press Windows key + I to open Settings, go to 'Windows Update', and click 'Check for updates'. Windows will now download fresh update files and should install successfully.

  1. Press Windows key + R to open the Run dialog. Type 'services.msc' and press Enter. This opens the Services window where you can manage background services. We need to stop the Windows Update service to safely delete its temporary files.
  2. In the Services list, scroll down to 'Windows Update'. Right-click it and select 'Stop'. If the service is already stopped, proceed. This halts the update process so we can clear out corrupted files.
  3. Press Windows key + R again, type 'cmd', and press Ctrl+Shift+Enter to open Command Prompt as administrator. Click 'Yes' when prompted. We'll use this to navigate to the SoftwareDistribution folder.
  4. In the Command Prompt, type the following command and press Enter: 'net stop wuauserv'. This stops the Windows Update service again (in case it restarted). Then type 'net stop bits' and press Enter to stop the Background Intelligent Transfer Service (BITS), which also handles update downloads.
  5. Now, open File Explorer (Windows key + E). Navigate to C:\Windows\SoftwareDistribution. Select all files and folders inside (Ctrl+A) and press Delete. If some files are in use, skip them for now. This folder stores temporary update files; deleting them forces Windows to re-download fresh copies.
  6. Also delete the contents of C:\Windows\System32\catroot2. This folder contains update signatures; clearing it can resolve corruption. Use the same method: select all and delete.
  7. Restart the services: In Command Prompt, type 'net start wuauserv' and press Enter, then 'net start bits' and press Enter. This restarts the update services with a clean slate.
  8. Finally, go to Settings → Windows Update (Windows key + I) and click 'Check for updates'. Windows will now download the update files from scratch, hopefully without the missing file error.
