Windows 10: Process called "MSCTFIME UI" stealing focus

I was playing video games on my computer when suddenly it paused for no reason. Thinking this was a random one-time occurance, I kept playing. However, the game paused again, and again after that. I thought that the game was losing focus, so I went to settings and turned off "pause game on focus loss" and that cured the issue. However, if I try to play a game fullscreened in windowed borderless, it will minimize randomly. I downloaded a focus logger from https://github.com/JocysCom/FocusLogger, and found out that a process, located in the folder C:\WINDOWS\Explorer.exe, called "explorer,"

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.

How to catch a process that steals window focus

One of my co-workers loses focus on his current window each like 5 minutes or so. Now I'm wondering which process steals the focus

I found this cool application focus.exe which will list the current foreground window - the window which has the focus.

Whenever the focus was stolen, the program printed this information:

As you can see the focus gets stolen by a process that could not been opened, so this information doesn't help me that much. What helps me, is that it still logs the processes PID.

So i wrote a little PowerShell Oneliner which should catch every new process that get's created and should output the process information:

But this didn't catch any of the PID's focus.exe pointed out.

How can I catch processes that couldn't been started, but still got a PID?
