Improve Registration workflow

[Omzig]

When running this in a powershell prompt it does not run it in the same space that PSU is running. You have to create a script inside PSU to run this and get it added. Unless there is some magical -parm that allows you to register it globally on the server.

Maybe we need a register button inside PSU to make this a smoother end user experience?
