CloseApps not working but Stop-Process -Force

We are trying to close a running Precess via closeapps, but the Welcome Message keeps popping up, even “Programme schließen” Button is used.
If we do not use CloseApps but Get-Process | Where-Object { $_.Name -eq “MyProcess” } | Select-Object -First 1 | Stop-Process -Force, everything works just fine, but our Users are not promted, that their Application will be closed. It just shuts down.
Is there an other Way then deferral?

PLEASE Close this Question.
I asked for a colleague with no english skills.

And NO Deployment skills!!!
