Windows 0x80070490: Fixing Update Failure Errors

The 0x80070490 error is often encountered during Windows Update, indicating a failure when trying to install updates.

This error may occur due to issues with Windows Update components, corrupt system files, or conflicts with software on your system.

To resolve the error, start by running the Windows Update Troubleshooter.

Open Settings, go to Update & Security > Troubleshoot > Additional troubleshooters, and select Windows Update.

This tool will scan for any common issues and attempt to fix them automatically.

If the troubleshooter does not resolve the issue, the next step is to manually reset the Windows Update components.

First, open Command Prompt as an administrator and type the following commands to stop the Windows Update services: net stop wuauserv, net stop bits, and net stop cryptsvc.

Then, navigate to C:\Windows\SoftwareDistribution and delete all the files in this folder to clear out any potentially corrupt update data.

Afterward, restart the update services by running the commands: net start wuauserv, net start bits, and net start cryptsvc.

Now, try running the update again.

If the error persists, you may need to use the sfc /scannow command to check for and repair any corrupted system files.

Finally, if that doesn’t work, consider using the DISM tool (DISM /Online /Cleanup-Image /RestoreHealth) to fix any deeper issues in the system image that may be affecting Windows Update.

If these steps fail, it could be worth resetting the Windows Update components using a tool like the Windows Update Reset Tool.
