Since last Windows 10 automatic update done on 8 PCs (KB5016616, KB5012170 & KB890830) 4 PCs are now showing "task host window is stopping background tasks" on shutdown.

Does anyone know what caused this?

Thanks

    Hello,

    An update of last Friday Oct. 28 apparently fixed the problem. I have 2 reboots without task host blocking the shutdown.

    Interestingly, it does not show under installed updates history of that day. Rather, it seems to be a reinstallation of some update from Sept. 15., namely: Cumulative Update Preview for .NET Framework 3.5, 4.8 and 4.8.1 for Windows 10 Version 21H2.

    So was it some outdated .net v3-4 range (current version is 6.0, why is the old stuff installed anyways) that was broken and causing the shutdown lock?

    I am not sure that this problem (Task Host Window stopping shutdown) is after an update or installation on both my win10 desktop and laptop of Win365.

    It also seems to be affecting backup to OneDrive.

    Any help to find a solution much appreciated.

    Thanks, Peter

    Since forcing the shut down is the only way to turn off the PC, how can I be careful about it?

    I suggest not stabbing the "Shutdown Anyway" in haste as I did. I now count to 10 before taking out my frustration, just to give it plenty of time to finish....

    Yep, I have exactly the same issue.

    For me it is since the two updates - KB5016616 and KB5012170.

    So I don't know if this narrows the culprits down from the 3 updates you mention.

    Hopefully this will be sorted soon. It's irritating.

    Yes, exactly the same issue here. Even uninstalling those updates doesn't fix the problem. Be careful using the "Shutdown Anyway" option as this corrupted my user profile and I had to use system restore to log back into windows! Hope somebody comes up with a proper fix soon...
