How to I stop MoUsoCoreWorker.exe from running or get it to run & end?

Next time when you unpause them, run the PowerShell command and see what you will get.

Note that IsHidden=0 means excluding the hidden updates.

The following will find installed updates.

Code:

(new-object -com "Microsoft.Update.Session").CreateupdateSearcher().Search("IsInstalled=1 and IsHidden=0").Updates|FT -property Title

It's been a while since I last looked at this thread (very busy) & I see a few updates.

For me:

1. Pausing WU updates has no affect on whether or not MoUsoCoreWorker.exe is added to powercfg /requests list.
2. Re: powercfg /requestsoverride process MoUsoCoreWorker.exe execution,
   
   Up until today I thought this wasn't working. What I expected is that MoUsoCoreWorker.exe would NOT be added. Today I found out that yes it gets added but Windows ignores. So yep this is working and with no apparent issues.

I also run the PS script above and this is what I got:

Code:

PS C:\Windows\system32> (new-object -com "Microsoft.Update.Session").CreateupdateSearcher().Search("IsInstalled=1 and IsHidden=0").Updates|FT -property Title

At this point I opened Settings -> WU and Windows had last checked a few hours earlier at 11:37am local time and there was nothing outstanding. KB5003537 was listed as a optional update.

I then checked for updates & Windows installed an update for Defender signature files and nothing else.

I have no idea why there are so many "updates" listed above. I haven't knowingly hidden any updates; in fact, I don't know how to do so in Win10.

Or am I misunderstanding what this list is?

Also, as pre Mark's post #62 above MoUsoCoreWorker.exe was added when I opened Settings-> WU it wasn't listed before.

Thanks to all.

I'm going to mark this thread as "Solved", since issuing the cmd:

powercfg /requestsoverride process MoUsoCoreWorker.exe execution

does allow the PC to sleep even though MoUsoCoreWorker.exe is listed in the list of power requests.

I still believe that this a "work-around" and not a proper solution but that would be up to MS to provide.

Also, in the months since I opened this thread the behaviour of MoUsoCoreWorker.exe has changed for me at least. It certainly doesn't appear as often as it did back in February and when it does it only remains active in the powercfg list for around an hour or so.

For me, that is usually in the morning when I switch the PC or wake it up from its slumber. More often than not, I'm using the PC for more than an hour so my PC wouldn't go to sleep anyway.

Cheers...

I just disabled "MoUsoCoreWorker.exe". As a result...



Nevertheless, I can still check for updates via scripts and WUMT.
