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

Steve,

Because the script uses Microsoft.Update your pause control must be affecting that as well as your WU itself.

I'm not going to be of any use to you then. Shame.

I don't pause updates because I rely [only] on metered connections & all access permissions being removed from USOClient [post #4 by TairikuOkami].
- Some small security-flagged updates do sneak past [such as the infamous KB4023057] but they have never bothered me or caused any update glitches of the kind that CUs & Version updates can.
- I only constrain updates so I can be sure of not getting them until I have completed preparations [such as making a new system image each month].

Perhaps WUMiniTool, WUMgr can list your paused updates?

I set my network connection to metered just now after reading your post, then disconnected and reconnected WiFi and unpaused Windows Updates hoping nothing would download without asking me .......... but the pending .NET Preview update started downloading anyway to my disappointment - so I disconnected WiFi to stop that.

Running your script lines after that still doesn't show that pending .NET update - I suppose because I've pause WU again.

WuMgr doesn't show pending Preview updates for me. I'll have to try WUMiniTool. Thanks for the help

UPDATE: Same results with WUMiniTool.

Updates that have started downloading continue to download when they get the chance even if the session has been interrupted as yours was. You'd have to clear it out [along with all other partial update downloads] by running the script in
Reset Windows Update - TenForumsTutorials
[Note this is significantly more comprehensive than similar scripts found elsewhere.]

- Metered connections stop updates from being downloaded
- Disabling USOClient used to stop WU from checking for updates but no longer does so.
- WU irregularly shows me a list of pending updates [that never download] and I'd have to disable automatic maintenance to stop the WU check running now.

- - I am reluctant to do that because I'd have to manually set up all its other useful functions so I just set it for a time the computer is normally off & clear its wake the computer checkbox [but I don't really achieve much by doing this].
- - Control panel, Security & maintenance, Maintenance, Change maintenance settings.

@Try3,
Yes, I did run the reset WU script after disconnecting from WiFi.

I don't understand why the Preview update starting downloading after I had set the WiFi connection to metered.

Maybe because I didn't reboot after changing it, but I did disconnect and reconnect WiFi after changing to metered.

You have to restart Windows for metered connection to take effect.
Are you talking about the following?

Then the behaviour has changed since the last time I had to endure WU [4 or 5 years ago].

I've looked at the tutorial and my related WU folders. The batch file script does not proceed until the relevant services have seen stopped [this being one of the reasons it needs to be run as Admin] and the only problem I ever saw was when it was run without elevation [until the services are stopped some of the update-related files can't be deleted].
- I have no additional information to help you, I'm afraid.
- It seems that with the new behaviour, you'll have to let that .Net update complete and then uninstall it so you can test the WU vaccine.

While checking my notes for the current topic [unsuccessfully] I stumbled upon my original reference for jobbing the USOClient
Allow only manual updates on Windows 10 [UsoClient] - gHacks Tech News

I meant to ask "Is there a way to show pending PREVIEW updates"

Code:

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

Maybe @Matthew Wai can shed more light on this specific issue?

Maybe the following article can shed more light, but I am not educated enough to make sense of it.

.........

The output just shows me one thing ..... a printer driver update which I have blocked. And again, my Windows Updates are currently blocked if that's a factor.

If you mean the "Pause updates" option, I have never used it and know nothing about it.

Yes, sorry, I've paused Windows Updates. After I make a Macrium backup once a month, I unpause and update, then pause again for 35 days (the max). Pausing prevents most updates from getting installed. Defender/AV signatures and updates still come through as I would want them to.
