Windows 10: Explorer.exe stealing focus and causing a mouse jumping

Hi,I have Windows 10 on the all-in-one Lenovo PC, and I have been recently experiencing a serious problem which makes working on a computer impossible. While working on my computer, all of a sudden, my cursor jumps into the geometric middle of a taskbar, together with changing the focus. I've had a serious problem finishing this post, and the browser lost its focus several times in favour of the taskbar, and I kept typing "out of focus".What I know so far:This glitch happens irregularly. Sometimes it appears twice in a minute, and sometimes it does not occur for 30 minutes.It happens regardles

mstsc.exe stealing focus

Hello.

I have a problem on my Windows 11 PC. Whenever I do anything on my PC, a program called mstsc.exe steals focus of my opened window. This happens every few minutes. The program is located in C:\Windows\System32\mstsc.exe. I used this program: focus to discover that this process is causing the issue and steals my foreground window focus.

How can I fix it?

Thank you.

 

Black Window Stealing Focus

First off, from what I can tell this is some sort of window. Windows can display over top of it, but only by bringing up or forcing the OS to show a window or item by hovering mouse over taskbar icon. The black window also is not fullscreen as anything being displayed behind it can be visible as a border around it (1 pixel on all sides).

I can't really say what is causing it. I have disabled searchapp.exe as it seemed to be randomly stealing the focus and it was being reported as the culprit by Window Focus Logger. Unfortunately it still happens from time to time, but focus logger now says it's Explorer.exe taking focus. I have tried terminating and disabling processes and services trying to determine what it is. The only way to remove it is to restart the computer. When doing so, before windows shuts down, the black window does close which suggests to me there is a process behind it.

Windows 10 Home Version 20H2 (OS Build 19042.804)

I will do what I can to provide any information request.
I am attaching 2 images, the first being what is displayed when it happens.

Any help would be greatly appreciated.

 

stealing focus while typing

Thanks for replying. That's not my problem though. I hate the touchpad altogether so I use a real mouse and have the touch pad disabled. No, the issue is literally background things stealing focus. any ideas for that?
