In a "StRaNgE" way, you sort of HAVE to admire this:
They've accomplished what technically isn't/wasn't accomplishable, w/out inserting yourself a validation computer of somekind into the internet connection that validates you (@ MS).
I'd have to guess that NO MATTER WHAT HAPPENS @ THAT POINT, they have redirected the validation code in the OS to say:
"THIS IS OK/VALID/LEGIT"
No matter what... right @ the evaluation code jump in the Operating System itself (probably boolean yes/no, 1/0 etc.) during its installation &/or validation period (like XP has etc., not sure how VISTA works it now though, I don't run it!)
