SU.PS1 Script

The following script allows you to run another PowerShell as a different user.  I use this sort of functionality when I’m testing software on another account (typically a standard user account).  I know, bad dev, I should be running as standard user instead of admin.  Oh well, I’ll make that switch when I move to Vista.

 

Save this script to a file called something like SU.PS1.
