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

Unfortunately when shutting down the original issue was still there.

It's a result of the last defender virus update - it's giving a false positive on Hive.NY which is part of anything based on the chrome browser.

Defender stops it and will find it anytime chrome (or chrome derived) browser runs.

Do not interfere - like allowing defender to ignore.

Hopefully it'll get sorted on the next virus update - or a patch. Until then you'll get a notification each time you start - and if you follow through to virus report /action, it will have been sorted.

Ignore and carry on. Not a virus or malware.

Trust me 😁

Now windows defender appears to hunt some process-infection, a complete scan is advised, I will keep my PC running for a while:

This might be another update-problem:

My system is up to date, including defender update today (during this session).

I wanted to shut down, but task host was preventing it. I'm curious whether this will be resolved after the next reboot.

Good oh! Job done.
