I used some BETA versions of the XP Powertoys and it didnt go very well. Only got the power calculator and the command line thing to work. Now the whole package has gotten a version detection scheme and will only install on a WinXP computer.
You can use "BandVWM" from STARDOCK, but I think it is a component of their ObjectDesktop (WindowBlinds, IconPackager, WindowFX,...). I have their software (around 40$) suite and think one can do amazing things... http://www.stardock.com
