Advanced RunAs is a more powerful version of the Windows RunAs function. With Advanced RunAs you can make more settings and create bat files with user credentials and command lines for whole installations. When a user logs on to the system you probably want to install some software like SP1a for XP, but the user doesn?t have the right permissions. Here is where Advanced RunAs comes in; with this you can put a command line in the login script that runs the installation with admin permissions.
