    Laptop won't go to sleep - process stuck?


    When I use "powercfg / requests" it shows that this process is running:
    \Device\HarddiskVolume4\System32\MoUsoCoreWorker.exe
    This has been going on for a few days. Laptop is on pretty much 24/7 and I have not restarted it
    lately.
    Anybody know what's going on? Should I kill it using Task Manager? Just restart and see what happens?
    Any suggestions would be appreciated.
    Thanks.

    USO Core Worker Process is a system process, related to the management, installation of Windows updates as well as new features of Windows 10.

    You might try checking your Update History (post a screenshot) - this may tell you about an update failing to install.

    Thanks for the info!
    I checked the update history (all types) and everything was "Successfully Installed".
    Just for fun I restarted (after saving everything that I had been sitting on). Afterward the troublesome process was no longer active, so I will consider this solved (for the time being).
    Thanks again.

    Oh, I think you're already out of date... see the News section where there's a thread per update per build..
