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

FBC1-0321 10

Hello!

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.

Thank you.

Check available disk space: Ensure that you have sufficient disk space on the Azure VM. Insufficient disk space can sometimes cause update installation failures. Make sure you have enough free space on the system drive (typically the C: drive) where Windows is installed.

Run Windows Update troubleshooter: Although you mentioned that the Windows Update troubleshooter did not work, it's worth giving it another try. Run the troubleshooter specifically designed to identify and fix Windows Update-related issues. You can access the troubleshooter by going to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Windows Update.

Clear Windows Update cache: Clearing the Windows Update cache can sometimes resolve update installation issues. Follow these steps to clear the Windows Update cache:

a. Open Command Prompt as an administrator. b. Run the following commands one by one:

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver c. Rename the SoftwareDistribution and Catroot2 folders. Run the following commands:

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

ren C:\Windows\System32\catroot2 Catroot2.old d. Restart the Windows Update services by running the following commands:

net start wuauserv

net start cryptSvc

net start bits

net start msiserver e. Restart the Azure VM and attempt the update installation again.

Check Azure VM configuration: Ensure that the Azure VM configuration meets the requirements for installing Windows updates. Make sure that the VM has a stable internet connection, is properly activated, and has the necessary permissions to access Windows Update services.

Contact Azure support: If the issue persists and none of the above steps resolve the problem, it's recommended to contact Azure support for further assistance. They can provide you with specific guidance based on your Azure environment and investigate any potential issues related to the VMs in Azure.

It's also worth noting that Microsoft regularly releases new updates and hotfixes, so periodically checking for and applying the latest updates may help in resolving this issue.

Thank you VasimTamboli for taking the time to share your input. I had shared that we had already tried some of the typical troubleshooting tricks such as the Troubleshooter, clearing the cache, emptying temp files, etc. These VM's were 1 weeks old and the April CU installed without issues..it was just the May CU that was failing at the 50% install. I also tried those CLI commands, out of curiosity, but no success...I had suspected the issue being something in the May CU and these new Azure VM images....we'll see if it get fixed by MS. Thanks.

Hello, @FBC1-0321 !

Thank you for bringing this to our attention. It appears that several people are reporting issues with this particular update on personal devices as well. I'm going to reach out to the PG to see if there are any known issues with this update and I'll put together information that I'm able to find from other sources as well.

Hello, @FBC1-0321 !

Following up, what VM size are you using?

Hello, @kobulloc-MSFT , thank you for the info and for looking into this. There are 6 VM's, which we deployed around the same time I posted the question. 5x Windows 11 Pro VM's are "Standard D2as v5 (2 vcpus, 8 GiB memory" (AMD vCPU, oddly Azure shows "Windows" Operating System in "Overview". 1x Win 11 Pro VM is "Standard D4as v5 (4 vcpus, 16 GiB memory)", same "age" as others, but this one does show "Windows 11 Pro" in the Azure Overview for the VM.

Thanks!

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:

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.

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.

@kobulloc-MSFT , thank you for the follow-up and your suggestion. That VM size was selecting due to its palatable $$ fees for the client. If we increase the size of the VM we'll be increasing the $$/month fee of at least 5x VM's...so I'm not sure if that is a suitable solution at this time.

We would much rather resolve the underlying issue, if possible. Yes, it'd be great if you would kindly open a case for us...please let me know what information you need as I could DM you with the necessary information. :)

Thank you!
