Silent .BAT files??

I've got a .BAT file in the start menu of all the machines we run our automation scripts on.  This .BAT file will update the registry to "turn off" the screen saver.  We have to do this for two reasons--1) QTP will bomb if a screensaver kicks in and 2) the Net Nazis where I work have disabled the GUI used to set the screensaver settings.

Yes I know its a hack but what choice do I have.

My problem with this .BAT file is this:  On 2 of the 5 machines, it runs completely silently.  No fuss no dialogs, nothing.

On the other 3 I get the "Would you like to make these changes to the Registry" dialogs.

The .BAT code is

REGEDIT /s /i screensaver.reg


 Which I thought would run silently and in 2 cases it does.   All five machines are Win XP Pro.

Is there anyone out there in the Geekdom who can suggest how to make this .BAT silent everywhere?

Much respect if you can.
