You do realize that's literally twice as many steps as it used to be, right? Go ahead and roll your eyes.
Before it was
1) open date/time properties
2) CHANGE ****ING DATE AND TIME!
(not yelling at you, btw - yelling at the ****tards at MS that thought this was a brilliant design decision)
I'm not sure if anyone has mentioned but turning off UAC would eliminate step 3. Personally I find the time/date functionality in Vista to be light years ahead of XP and just one of the many improvments in the OS.
BTW, performance in Vista is at least equal to XP now on the latest drivers with SP1.
