very nice help. 
at the moment I have the problem that I want to give the powershell script parameters. 
Do you know the right way? 
  
thats my test (tried with ' and "): 
ServiceUI.exe -process:Explorer.exe %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile -WindowStyle Hidden -ExecutionPolicy RemoteSigned -File ".\script.ps1" -Message 'Hello,' -Title 'Test' 
  
When I run it on the local system in the powershell with this everything is nice: 
.\powershell.exe -NoProfile -WindowStyle Hidden -ExecutionPolicy RemoteSigned -File ".\script.ps1" -Message 'Hello,' -Title 'Test'  
  
  
When I write the parameters in the script itself everything is ok with this: 
ServiceUI.exe -process:Explorer.exe %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile -WindowStyle Hidden -ExecutionPolicy RemoteSigned -File ".\script.ps1" 
  
  
So now I dont know how to write it correctly in the SCCM (maybe wrong use of " ' ) ...on the local computer everything works fine
