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

    Since last update having same issues when attempt to power off computer. Receive the infamous 'Task Host window is stopping background tasks.'

    At same time, Power Options do not function correctly. In control panel, always shows "Your power plan information isn't available." Help assistance from Microsoft says this is 'directly related to Windows Update' and to run the Update Troubleshooter and Power Troubleshooter... both of which produce no fixes. Computer will not go to sleep or turn off display after extended period of non-use.

    If I shut down or restart computer within first 20 to 30 minutes, I receive no errors. But if longer than that, the system hangs at the 'Task Host window' screen and then goes to the login screen after about minute+... computer will not shut down or restart without clicking 'Shut down anyways.'

    Have looked at event viewer and since 8/16/2022 (which was when update was installed), have multiple errors at times when I've attempted to shut down/restart computer... all with similar errors:

    • the attempt by user to restart/shutdown computer failed
    • session perfdiag logger failed to start with the following error: 0xC0000035
    • session 'PerfDiag Logger' stopped due to following error: 0xC0000188
    • Microsoft Office Alert 16 event ID 300
    • Microsoft.Windows.Remediation failed to start with the following error: 0xC0000035
    • Cloud Files Diagnostic Event Listener failed to start with the following error: 0xC0000022
    • NT Kernel logger failed to start with the following error: 0xC0000035
    • Microsoft.Windows.WindowsUpdate.RUXUMLog failed to start with the following error: 0xC0000035

    Over 720 event errors since the update on 8/16/2022.

    I tried this method and it worked. Now I will leave the machine up for a couple of days and see if the success continues

    I'm sorry if I misunderstand, but it seems that Christopher's post details some solid observation, but doesn't, as far as I can tell, offer a solution. And that's fine - it's a step in the right direction!

    But I don't understand what 'method' you have gleaned from it. What have you tried that worked?

    I'm sure I'm missing something very obvious here! Please let me know!

    Same issue, tried everything as recommended and even ran half a dozen malware/rootkit/virus tools - nothing detected.

    Issue persists, no resolution. Please if anyone knows reply with your troubleshooting tips.
