Before you start troubleshooting with the methods below, it’s important to crosscheck for a software conflict.

Note: If you don’t have an external antivirus, go straight to Method 2.

But even if Windows Defender is disabled, some external anti-malware suites aren’t quick to grant the necessary permissions for the updates to complete. To make sure this is not an issue caused by your antivirus, disable the real-time protection and the firewall from it. Then, restart your machine and attempt to apply the update again.

If the update completes successfully, you’ll need to reinstall your 3rd party antivirus or look for a better option. If you encounter the same 0x80070490 error, move down to Method 2.
