Steve Gibson of GRC fame spits out another useful tool:

It simply displays if some newer hardware features are available on your PC. The screenshot is verification that the 64 bit PC I built almost three years does support DEP.

DEP: Prevents buffer overflows in hardware - this a very big deal. Of course the operation system must support DEP too. Which versions of Windows support it is unclear, but 64 bit Vista and XP should support it. Hopefully Steve Gibson will extend his utility to test DEP with an actual buffer overflow
Hardware Vitalization: Hardware support for running Virtual Machines - they should run with no speed degradation

You can see all of Steve's free utilities at his circa-1995 website:

After a period of dumbing down his Security Now podcast is again one I highly recommend:
