    I made a series of mistakes. I tried Malwarebytes, but did not like it, so I deleted it using its own uninstaller tool. Later I discovered elements of Malwarebytes were still in a folder called ProgramData. My first mistake was thinking I could/should remove all traces of Malwarebytes since I’m not using that program.

    I then ran Revo Uninstaller but Win10 Security said I needed Admin permission to delete this folder.

    I thought I, as the user, had admin rights along with two other resources “SYSTEM” and “Administrators”. I found all three names under “AppDataProperties / Security / Group or user names”.

    I tried to remove “Administrators” from this list, but Windows Security said I can’t “because this object is inheriting permissions from its parent…(you) must prevent this object from inheriting permissions. Turn off the option for inheriting permissions….”. Needless to say, I am now in deep water because I don’t know what Windows Security means when it talks about inheriting, parent and option! But I press forward….(my second mistake)

    I ran this command three times:
    (1) “C:\WINDOWS\system32>net user administrator /active:no – The command completed successfully.”

    (2) Then I ran the same command but changed “active:no” to “active:yes” – The command completed successfully. To my dismay, this action seems to allow both the “Administrators” and “me as the user” to simultaneously run many of the same process and programs; one in  the foreground, and one in the  background.

    (3) Then I reran the “C:\WINDOWS\system32>net user administrator /active:no – The command completed successfully.” – I though “active:no” would undo everything I did before I started meddling around.

    But, Task Manager still 20 or so identical process running simultaneously. Examples include: Notepad, Device Association Framework Provider Host, Host Process for Windows Tasks, NVIDIA Container, Runtime Broker[ four processes running], Sink to receive asychronous callbacks for WMI client application, and many more

    My question is this: how do I stop duplicate processes from running simultaneously?

      You don’t, because you shouldn’t.

      I don’t have the technical knowledge of the internals of Windows to explain this in detail, but most of those are handling different underlying functions of Windows. Disabling them without intimate system knowledge could do more harm than good – some Windows features you use might stop working.

      Though I will say that as far as I know, Notepad should only show up if it has been run by someone, and then only under the Apps group of the Process tab in Task Manager (when sorted by Name). And then I’d expect there to be one or more taskbar buttons for Notepad. If there aren’t any, you might try rebooting to see if Notepad appears to automatically run itself again.

      NVIDIA Container is installed with NVIDIA drivers on machines that have NVIDIA graphics. Maybe you don’t use any of the functions of the NVIDIA control panel or other NVIDIA software and could disable it. But if your use case changes in the future you may find yourself wondering why some NVIDIA feature doesn’t work.

      The reason there are multiple “same name” processes running is because, unlike previous versions of Windows where all the sub-processes that make up a particular program were all run by one master process, each “sub-process” is now run in it’s own separate sandbox.

      That way, if a particular “sub-process” stalls/crashes, it doesn’t cause the whole program (and/or Windows) to lockup/crash.

      This is especially true for modern browsers…

      I.e., when I run MS Edge, Task Manager shows a large number of Edge instances running and the number “increases by one” for each new tab I open.

      If one of those tabs encounters a problem that would normally crash the whole browser, sandboxing allows only that particular tab to crash while MS Edge and all the other tabs still work!
