Hi there, I installed Windows 7 Ultimate and used Technet key from a friend to activate. I backup 2 files: tokens.dat & pkeyconfig Now I reinstall Windows 7 ultimate and want to replace the old tokens.dat & pkeyconfig to new system. Unfortunately, The Technet key is now over 10 activation times. I'm wondering if someone know how to replace the tokens.dat & pkeyconfig ? and Can we use 2 backup files and old key to activate offline ?? Any suggestions and help would be appreciated. Thanks a lot in advance.
