Early Windows Vista adopters should still remember the native hack to activate Windows Vista by using the free product key from beta or RC phase after replacing two activation related files namely pkeyconfig.xrm-ms and tokens.dat with beta or RC editions. Microsoft then cracked down on the these frankenbuild activation crack method in new WGA update, effectively forces hackers to move to better Windows Vista crack method.

But it appears that the backdoor is left opened once again, and hackers and Windows 7 enthusiasts quickly take advantage of the loophole to activate Windows 7, even though Microsoft hasn’t officially released any product key of Windows 7 for public usage.

The crack works due to Microsoft allows Windows 7 Build 6801 to be activated with Windows Vista Beta or RC keys. As such, the pkenconfig.xrm-ms and tokens.dat (in Safe Mode) from Windows 7 Build 6801 are extracted and been used to replaced the original files in Windows 7 Build 7000, and then users can activate Windows 7 with J7PYM-6X6FJ-XXXXX-XXXXX-XXXXX Vista CPP product key.

However, the frankenbuild crack is not a long lasting solution, as Microsoft likely to plug the loophole once Windows 7 is finalized and released to manufacturing (RTM). Beside, if users go to Windows Update trying to update Windows 7 activated with frankenbuild method, WU will detect that the copy of Windows 7 is not genuine, saying that “You may be a victim of software counterfeiting” and error message “Optional update delivery is not working.”
