Bala_Delli thanks, this is the log I've been reviewing, in this log I could see "Unable to read existing WUA Group Policy object. Error = 0x80070002." on the affected clients, other logs connected to update installation process showed that there is a timeout.
- Can you please comment on the "Allow clients to download delta content then the option is available" client setting, if it should be mandatory to set to "Yes"?
- If yes, should this be set to "Yes" for all operating systems in the environment or are there any exceptions? I'm asking as there is a thread on the same issue on Servers https://learn.microsoft.com/en-us/answers/questions/1286246/mecm-software-updates-for-ws-2019-2022stuck-at-0-d, where the solution is to set this client setting to "No" - which is confusing for me, especially when only a part of the devices that I manage (Windows 10 21H2) has the problem.
