A Windows 7 build that may be the first release candidate has leaked to the Internet, according to several file-sharing sites.

Searches on Mininova.org, for example, found multiple copies of Windows 7 Build 7057 that have been added to BitTorrent since yesterday. Pirated versions of both 32- and 64-bit editions are available.

The appearance of Windows 7 Build 7057 follows the leak of Build 7048 by just a week. This newest edition is the third to hit BitTorrent since Microsoft stopped offering the public beta of Windows 7 last month.

Traffic on Build 7057 has been lively. As of mid-day Friday, Mininova reported that one 32-bit BitTorrent of the operating system had been downloaded more than 37,000 times.
