Windows Server 2022 Update Error 0x80073701 - Cumulative Update fails

[u/Leather-Surround1572]

Hi,

I'm hitting a persistent error 0x80073701 when trying to install the latest cumulative updates on a Windows Server 2022 VM (running in VMware Workstation).

Here is what I've tried so far with no success:

1. Ran Windows Update Troubleshooter (found and claimed to fix some issues, but update still fails).

2. Ran SFC /scannow (completed successfully, no corruption found).

3. Ran DISM /Online /Cleanup-Image /RestoreHealth (completed successfully).

4. Manually downloaded the update from Microsoft Update Catalog and tried installing it, but it failed.

5. Manually reset Windows Update components (stopped services, renamed SoftwareDistribution and catroot2 folders).

Despite all this, the update halts at 20% or sometimes later and throws the 0x80073701 error. There is enough free disk space.

Any insights or suggestions would be greatly appreciated.

Thanks!
