  2. Disconnect any active VPN and retry the update.
  3. Run Disk Cleanup with "Clean up system files" checked.

Frequently Asked Questions

Is this related to low disk space?
Yes, it's one of the most common causes — this error frequently appears when there isn't enough free space for the update to complete, particularly for larger feature updates.
Could a VPN cause this error?
Yes — an active VPN can sometimes interfere with Windows Update's connection to Microsoft's servers, so temporarily disconnecting it is worth trying if space isn't the issue.
