Hi, neither Vista nor W7 were cracked so far. Activators / cracks are useless! They are using licensing files from RC version. Such frankenbuid versions will be disabled by m$ at once and they will never survive WGA check. Additionally you'll get a timebomb again (expiring date) Only way is to wait for SLIC /cert./ SLP2.1 combination either via biosmod or via softmod loader. This will take some time since there are no serials /certificates leaked so far. In the meantime enjoy your un-activated W7 and rearm it if needed. Don't cripple it by exchanging licensing files.
