Mouso core worker process

That's it! Your a legend. Thanks mate. I've tried everything beforehand, countless system restarts, service restarts, update checks... nothing. No new updates found. I disabled updates for 7 days, re-enabled it and it immediately found and installed 2 updates (KB4601554 and KB4577586). Now the problems seems to be gone.

I also had the "no sleeping" problem with MoUso. I disabled updates (for 7 days), a few seconds later re-enabled updates. The updater found update KB6401554, installed it and now everything is good. An easy fix (for the moment), a PITB to search for the solution. Thanks for the help, I hope it lasts the test of time!

i have had this same problem on my pc on windows 10. Could NOT figure it out did research for hours . pulled up command prompts and only thing it said was i needed to preform an execution for mousocore worker. Even tried an override code . nothing worked, Finally i got the bright idea to go to task manager find mousocoreworker.exe running under backround processes and right click to end task. Working fine now and my computer went straight to sleep after. hope this saves some time and frustration for someone

My computer (Windows 10, 64-bit Build 19041) is constantly waking up from sleep and then going back to sleep for a short time only to repeat the cycle.  I ran sleep diagnostics on the Windows PowerShell as administrator i.e. powercfg /systemsleepdiagnostics.  The report from yesterday (5/31/2020) indicates that my computer awoke from sleep 50-55 times during the course of the day until at about 8:00 p.m., I decided that it was better to fully shut down the computer rather than have these continued cycles.  The common thread in all these awakenings from sleep is MoUSO Core Worker Process (MoUsoCoreWorker.exe).

This executable is a Microsoft programming element. 

 Why is this happening and what can I do to eliminate this totally annoying phenomena?

Go to Services > Windows Update and right click on "Manual (Trigger Start)" in the Startup Type column and then in the popup dialog box that appears click "Restart". This eliminates the MoUsoCoreWorker. exe in the Cmd window when you run powercfg -requests.

More specifically, every month they revert our computers to the same screw-up they introduced almost a year ago, which is an order of magnitude more reprehensible than the new bugs they introduce somewhat frequently and then scramble to correct.

So obnoxious and egregious is this MoUsoCoreWorker bug that it leads me to believe that all Microsoft supervisory personnel have lost touch with the Windows user experience entirely. Had they not, a single command from on high -- "Fix this before EOB today!" -- would certainly have been sent many months ago.

BillG, where are you?

(Meanwhile, my Macs get updates periodically and go years between problems caused by them, while the update process, itself, has remained problem-free for decades.)
