Let me start with a strange situation I have. Last week when the now infamous WAT update was instituted by M$ to foil the bad fellows who pirated their Win 7, I had performed five installs earlier on different machines for a beta run to see if they would be compatible with in house applications, unlike Vista, Win 7 was. So on the very Tuesday Feb 16th when the new legit check was instituted, being curious I ran the validation check on each machine to see if it would pass. All machines were loaded with the leaked Windows 7 Ultimate OEM_Retail iso and were activated with the Hazar-Orbit30 loader, no Chew, no WAT remover. After running the new validation test on M$/genuine, I have 3 machines that validate right up to before posting this, and 2 that do not. So for those on this forum that have the technical knowledge and understanding of systems...what is taking place on the machines that is different, to allow validation?
