Windows 8 leak season is in full swing and today we’ve learned that a leak of an early Milestone 1 build of Windows 8 has been posted to a BetaArchive FTP site. So far, the build is only available to private members, but is said by many to be legitimate and will soon be available to the public through the wonderful, albeit sometimes shady, world of torrent sites.

The build is listed as: 6.1.7850.0.winmain_win8m1.100922-1508_x86fre_client-enterprise_en-us.iso – 2.45 GB

Windows 8 has already passed Milestone 2 and is said to be nearing M3 with a beta to come later this fall. While many sites confirm the authenticity of the build, I would not recommend any users rush out to download and install this one especially as your main OS. Keep in mind this is an older build (possibly September 2010), so many Windows 7 elements may be present.
