The upcoming Windows 7 beta found its way onto the Internet late last month amid favorable impressions from those who gave it a try. Specifically, Windows 7 build 7000 32-bit was leaked back then, and now the 64-bit version
has also made its way to several file sharing sites as well.
Interestingly, Microsoft may not be overly displeased with the leaks. The arrival of Windows 7 beta code on file-sharing sites has resulted in rocketing interest in the next-generation operating system on search engines – and it is currently the most popular software download in the Pirate Bay's Top 100. A public beta is also expected to be announced at the CES 2009, so you may want to wait, though it's not clear when the actual download will be available.
