Can someone please tell me if Tokens.dat is changed after updating. I have a retail version of W7pro 64 bit what is activated at octobre 2009. Beginning of march 2010 I got sometimes the NonGenuine message and the asking to validate, what I not have done because I don't want the KB971033 update if there is something wrong with my install. The online validation, if I want to download something from MS, is OK. I have run several times MGAdiag after I got this message. The program write logs in the programdirectory "MGADiagToolOutput" by cabfiles. Within these cabs are 2 files. One is Tokens.dat. I have compared these Tokens with Total Commander and they are al different. Because of this I have replaced my backup of Token.dat from octobre 2009 and till now I don't got the message anymore.
