Since last Windows Update "task host window is stopping background tasks windows 10" on 4 machines

I thought it was fixed. The Taskhost preventing shutdown is back for me again since yesterday, after 7 reboot/shutdown cycles :(

The update which appears to have fixed it for me is the Quality Update 2022-10 Cumulative Update Preview for Windows 10 Version 22H2 for x64-based systems (KB5018482) Have had several clear reboots since installing it so am really hoping that’s it now.

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So was it some outdated .net v3-4 range (current version is 6.0, why is the old stuff installed anyways) that was broken and causing the shutdown lock?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 found this other similar thread which seems to at least help identify which program or app is preventing shutdown: https://www.windowsdigitals.com/closing-1-app-and-shutting-down/

However, so far I haven't been able to confirm: I found two WINSRV entries in the Windows log/application:

camtray.exe

brstmonw.exe

Am hoping that will be permanent, my PC shut down OK after that update, the crunch will come when I use the PC again later this week. That has happened before, fine after an update then back to square one. Fingers crossed this time. Microsoft really need to fix this!
