Good afternoon!
Tia portal 15.1 Wincc pro.
I have a runtime that runs when a user logs into Windows 10,
but there are many users on the computer who also need to use
 this runtime. But I can’t run two runtimes. Some users don't
 do a system reboot or logoff, just sign out. Tell me some 
solution on how I can launch the second runtime and
 deactivating the first one.

This can be a Windows problem needing a Windows solution. How about making a Powershell script or Batch script (*.bat)? I have quickly web searched for something like "batch file detect process running" and "powershell check if process running and close it".

The nice thing about making a BAT file is that you can place it on the desktop and have people run that instead of starting the Wincc runtime.

Only for inspiration..
