Hello

Thank you for posting in Q&A forum.

Here are some steps you can try:

1. Ensure there are no pending reboots from previous updates. Sometimes, a pending reboot can cause issues with new updates.
2. Delete the contents of the SoftwareDistribution folder to resolve issues with corrupted update files, then restart the “wuauserv “services.
3. Download the update manually from the Microsoft Update Catalog and install it. This can sometimes bypass issues encountered during automatic updates.
4. Ensure all network drivers are up to date. Outdated drivers can sometimes cause issues with updates.
5. Use the System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM) to repair any corrupted system files:

sfc /scannow

dism /online /cleanup-image /restorehealth

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.

Answer 3

Hello,

thanks for you advice. I tried everything from your list already.

Yesterday in the evening I removed the Hyper-V Network Adapter from system completely to try the update without anything network related and installed it manually from Update Catalog, but still the same error.

Is there a way to update the Driver for Hyper-V network adapters?
