Mouso core worker process

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).

- \Device\HarddiskVolume5\Windows\System32\MoUsoCoreWorker.exe | START TIME | DURATION | TYPE | TOKEN | | --- | --- | --- | --- | | 2020-05-31T18:18:53 | 0:00:01 | Execution | 0xffff8389192ab2e0 |

This executable is a Microsoft programming element. 

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

    Ok, here's another example of the MoUSO issue. Core i7-3520M, 2.9GHz-3.6GHz. I'm installing a new Win 10 21H1. I just didn't the 2021-08 Cumulative update and the button for Restart Now is visible. I minimize the Settings window, and when I restore the window MoUSO uses 50% CPU for 24 seconds, I timed it. Every time I restore it, 24 seconds of 50% CPU. And this is on a 3rd gen Core i7 which runs at 3.44GHz for that duration.

    I just rebooted, and the update is installed. I open the Windows Update page, and now when I minimize the page and restore it for seconds the 50% CPU usage is split between the Settings process and the MoUSO process. Every time I restore the non-active Windows Update window, 10 seconds of 50% CPU.

    Rapidly clicking on the taskbar Settings gear icon results in a very slow minimize and restore of the Windows Update window. When I go to the Settings Home screen, it's not like this. Very very fast minimize and restore of the window. So even as of August 2021, MoUSO is broke and inefficient.

    They need to fix what they already have instead of making a new OS that can only be installed on computers manufactured in 2016 or newer. But maybe that IS their fix for the broken MoUSO, buy new hardware.

    EDIT: Oh, regarding your PS: above, check your Fast Startup in the power settings. I've seen numerous computer hang on the first, then a power cycle lets it boot properly. This happens after you select Shut Down and then boot up. A Restart shouldn't show the issue, only after a Shut Down. So disable Fast Startup if this applies to you.

    I got mine fixed but can't remember what I did?  Maybe something in Services.  Sorry.

    I did not get mine fixed.  Just thought I did.

    I have a second PC which does not have KB4568831 yet. It has just gone to sleep for the first time in 5 days.
