Whats the purpose of this? I don't think what your are trying will work, UEM is designed to redirect folders, zip up configurations, but not actually move the profile. While I'm not 100% but I don't think you can do anything to that file while you are logged in as that user.
I'm referring to ntuser.dat
Actually, I need a mechanism similar to Persona Managment. It works great for me on Windows 7, but unfortunately RDS is not supported. That is why I have to try UEM.
Ntuser.dat stores important program settings for us.
