What do I have to install to get screen rotation?

[devilsrejection]

I'm on a fresh install of Vista, I don't like to install any TP software seeing as all my drivers were found. So far I had to install the hot key application to turn on bluetooth, then the bluetooth software, 2 exe's aren't that bad.

what do i need to install so that my screen auto rotates when i stick it into tablet mode? thanks!

I believe it's an option in the control panel. Not sure where though...
