So far, near as i can tell, the biggest change is the Aero graphics. if that is adding 14.9 gigs of space... wtf...

The key things still haven't changed, we still BSOD, we still have memory leaks, we still require virus and anti malware scanners.

So are we talking things like UAC?
I bought a car that specifically didn't have traction control? Why? out of all rental cars I have driven, the traction control ones are the most irritating, especially in the winter. Near as i can figure, it displays a light when you are sliding (So did my Lumina with ABS, the result is the same) and retard the engine when you need to deperatly accelerate. Again, especially bad in the winter, a tiny bit of ice spin and the stupid thing tries to stall the engine in the middle of an intersection. Stuck in the snow? not a chance, it kills the engine again.
Worthless crap.
