Thx you 2
I testen those registry settings on my own workstation that is in a domain and they worked for me. it are settings like :
Dont group simular programma's in the taskbar and add some defualt icons on desktop etc.
I have all of those in a reg file as you know and i just want it to load when a user logs in.

so this :

$regfile = ""c:\marcel\netwerk-policy-settings.reg"
shell 'regedit /s "'+$filename+'"'

Should work then with kixtart ?

thanks alot!
