You might try looking at this page for some ideas: http://www.codeguru.com/cpp/w-p/system/hardwareinformation/article.php/c9087__2/ It gives 3 ways to get processor information: - assembly (pycpuid uses this) - registry (there is a key in the registry that stores this info, but it looks like it's all ORd together, so you'd have to decode it) - Platform SDK ( IsProcessorFeaturePresent() is probably the function you want ) The page has some C++ sample code, which might help you some. I'd probably either try to read the info from the registry (though you can't be 100% sure the registry is correct, of course), or figure out what C functions to call and wrap them up in ctypes calls. How to integrate this with your WMI code (is it querying remote machines?) is up to you. :) But feel free to ask if you need ideas. Kevin Horn
