15 Windows 7 Pre-Beta Activation Keys
Windows 7 M3 (build 6801) was leaked over the Internet through torrents a few weeks ago, which was free and easy to download. But you still need a valid activation product key in order to use Windows 7 on your system or you will only get a 30-day trial.
Later it was found that the old Windows Vista Beta and RC product keys can be used for Windows 7 Pre-Beta as well and you can activate your copy using it.
Hereâ€™s a list of 15 Multiple Activation Product Keys (MAK) that you can use to activate your Windows 7 (32-bit and 64-bit editions).
These keys can be used on unlimited number of systems, and you can activate Windows 7 online or by phone activation.
