If you open up your eyes a little and do a little searching you'll likely stumble into Windows 7 beta 1 (build 7000) on the web as it has leaked to torrent. The Windows 7 Beta1 full ISO image can be found on sites like DepositFiles, Demonoid and Mininova.org.

Another alternative way spotted to download is by using Namipan file hosting (net disk or web drive space) service. Namipan is a China based file hosting service.

The ISO image is the full version DVD image that allows installation of all editions of Windows 7 similar to Windows Vista, namely Windows 7 Ultimate, Windows 7 Business, Windows 7 Home Premium and Windows 7 Home Basic. After installing, Windows 7 has the version of 6.1 (Build 7000).

The beta will expire on July 1, 2009.
