I'm in the process of using Azure Update Manager to handle patches for our on-premise servers linked through Arc, and most of it is going smoothly. However, I'm having trouble with a few servers that run .NET Core 8.0 for some web applications. The October 14th update for .NET Core didn't get installed through AUM. I came across some info suggesting that we need to enable the setting for installing updates from 'other Microsoft products' either locally or via Group Policy, which we've now done for these servers.
Despite this, the .NET Core update still doesn't show up when scanning with AUM. Is there anything else I might be overlooking to resolve this issue?

Don’t forget that enabling the Microsoft Update option via Group Policy means you'll need to restart the Windows Update service for the changes to take effect. You can check if it’s enabled by querying the registry. If everything looks good, manually restart 'wuauserv' and run a Windows Update detection to see if it finds anything. Azure Update Manager relies on local Windows Update functionality, so if that's not working, AUM won't show any updates either.
It can take a few days for Azure Update Manager to recognize new updates after enabling that Group Policy. Just give it some time; I've seen it take about 3 to 4 days, so be patient!
If you also have Ubuntu servers to patch, be aware that Azure Update Manager can be quite hit or miss for those—I've experienced it working only about 30% of the time!
You might want to check a registry key that allows .NET updates when the 'other Microsoft products' option is enabled. I can’t recall the specific key, but it’s worth looking up to ensure it’s set correctly.
It's possible that .NET Core wasn't installed in the typical way, which might cause it not to be recognized by AUM. Make sure the installation method aligns with what's expected by the update services.
