W2k/XP - Keep the Window visible on login?

Works very well, if you have the right permisions to write in the registry.
But our users doesn't have those rights.

How can we put that key in the registry without consulting a administrator to log on and off? We have over 200 clients in several locations.

I would be greatful if someone has the answer.

Thanx,
Mike

NOTE: I also change "IF @dos = 5.0" to "IF @dos >= 5.0" so it works well with Windows XP.
