- Click on Start > Power > Restart.
- Once rebooted, check if the error persists.
Step 2: Run Windows Update Troubleshooter
Windows comes equipped with built-in troubleshooters that detect and fix common update problems.
- Press Windows + I to open Settings.
- Navigate to Update & Security > Troubleshoot > Additional troubleshooters.
- Select Windows Update and click Run the troubleshooter.
- Follow the on-screen instructions.
- Restart your PC and check if ERROR_440 is resolved.
Step 3: Clear Windows Update Cache
Sometimes, corrupted cache files block updates from installing properly.

Step 5: Use the DISM Tool
If SFC didn’t fully resolve the issue, DISM (Deployment Image Servicing and Management) can repair the system image.

-
Enter these commands one by one, pressing Enter after each:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth - Allow each command to complete. This process can take 10-20 minutes.
- After completion, restart your PC and check for improvements.
Step 6: Update Windows Manually
If the automated update process is still failing, try installing updates manually:
- Visit the Microsoft Update Catalog.
- Type the KB number of the update you want to install (find this in the update history section).
