Here is a minor change you may notice, as Windows 7 is rating Q6600 beyond 5.9 mark which happens to be the highest possible rating under Windows Vista SP1.

By so far, I have installed the product on at-least dozen PCs with alternate configurations from all types of platform, AMD / Intel, Nvidia / ATi / Intel, Laptop / Desktop and till now it really seems to be a stable OS with no BSOD yet.
