NFS4,
PM me and I will hook you up with the new powertoys.
Frankly, they don't do very much... you can go to the windows super site to read a nice blurb about each one of them. The only one's worth having IMHO are TweakUI and the "command prompt here" powertools.
In a side note, I installed TweakUI 1.33 and uninstalled it in add/remove programs but it won't go away.
