New Application: CPUID Explorer

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I've uploaded a new utility program that shows how to use the CPUID instruction to
investigate the properties of your machine. It is now available from my MVP Tips site.

This is still a work-in-progress but I wanted to get it up before I leave in a few hours
for the MVP summit.

I'm soliciting machine description information, so I'd appreciate if you could download it
and run it, go to the system menu, select Write CPUID info, and send me the resulting
..cpuid file, which I can use to test out what it tells me about machines I don't have
access to.
