Azure VM, KB5026372 install error in Windows 11 Pro 22H2 x64

KB5026372, 2023-05 Cumulative Update for Win 11 Pro 22H2 x64 keeps failing with Install error - 0x80070246 on all Win 11 Pro 22H2 x64 VM's in Azure...all 6x VM's. The same KB installs with no error in other regular PC's. There must be something in this update that does not agree with the VM OS image?

The Troubleshooting, Windows Update, does not work, clearing the cache does not work, reboots don't work...nothing works.

Any help or tip would be appreciated.

    Hello, @FBC1-0321 !

    When attempting to update my Windows 11 VM with KB5026372, 2023-05 Cumulative Update, why do I keep getting a failure with Install error - 0x80070246?

    I reached out to the VM product group to get some additional information on this and there appears to be some issues with Windows 11 upgrades that are related to the underlying hardware for specific VM sizes. This is currently under investigation and additional information may be available later on.

    For now, there are 2 things that we can do to get you unblocked:

    1. Change the VM type or increase the VM size. Doing this may address some of the hardware requirements that Windows 11 needs for the update.
    2. We open a support ticket. We can open a support ticket for you that would allow backend engineers to look at your specific VM setup to determine what the issue is.

    Let me know which direction you would like to go (or if the size change worked). Hopefully this will get you back up and running quickly.
