I have my own set of tips for Windows Vista -- some secret, some not -- that apply mainly to laptop and Tablet PCs, so I thought I'd share.
#1: Windows Mobility Center
Windows Mobility Center is a great one-stop portal for managing a LOT of settings on your laptop or tablet -- power scheme, audio volume, screen brightness, projection, rotation, as well as one-click access to myriad other Control Panel applets for stylus input and handwriting recognition.
It's definitely not meant to be a "secret", but for some reason we really did bury it in the Start / Programs / Accessories menu... Place a shortcut to
MblCtr.exe on your Quick Launch bar, or pin it to your Start Menu, for easier access.
Update: Reader benwatt reminds me that [Win+X] will launch the Mobility Center -- for laptops and Tablet PCs with keyboards!Continue At Source
