>I wrote a program to detect HyperThreading (HT) using WMI. Would you mind testing on your machine(s)? It only works on Windows XP SP3, Windows Server 2003, and later, because that is when MS introduced the required APIs. Other than that, the only requirement is that you actually know whether or not your hardware supports HT. I would like this tested on machines that have HT and those that don't, but please report which you have with your results. Thanks! I appreciate the help.
Worked fine on my laptop (I have hyperthreading enabled), under Windows 7 x64:
CPU Manufacturer: GenuineIntel
CPU Name: Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz
Number of Physical Cores: 4
Number of Logical Processors: 8
HyperThreading is ENABLED
