Hi,
"Install pending" status during updates is usually caused by component corruption or the specific update management method used in your environment.
We recommend manually installing the update via DISM. This helps isolate the exact error code or issue by reviewing logs after the manual attempt.
Regarding your question about policies or registry settings affecting updates, it’s honestly difficult to determine without case-specific analysis. Manual installation via DISM is the first step to narrow down the root cause, after which logs can reveal whether a policy or registry setting is involved.
To proceed, we strongly suggest checking for corruption, restarting all relevant services, and running the DISM installation. If you're still interested in exploring policy or registry configurations, you can refer to the official documentation here: https://learn.microsoft.com/en-us/windows/deployment/update/waas-wu-settings
Hope this helps! Feel free to reach out if you'd like to discuss further.
