Its workting, or lets say that we are fooling the user so they think its is fast..
I have set the registry file to 5 seconds, and users see "preparing wondwos" for just 5 seconds, even total logon time is almost 30 seconds.
From the log file:

If i remove this registry setting, it will take almost 30 seconds to log in, but it will display "preparing windows"....
But it is great, since users can see that things are happening, and that they are loged on to windows pretty fast.
i have also added some registry keys to turn off visual effects witing UEM, beter performance with a fast startmenu :
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\VisualEffects]
"VisualFXSetting"=dword:00000002
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Serialize]
"StartupDelayInMSec"=dword:00000000
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize]
"EnableTransparency"=dword:00000000
