It was just last week that build 7955 leaked to the Internet, but now, according to BetaArchive, build 7959 has been leaked. This build represents the first M3 build to be leaked but is said to be quite buggy. It should be noted that this is a server build, unlike the previous leak, 7955, which was of the Ultimate variety. This build weighs in at 2.87GB and is said to be an X64 build.

I'm downloading from BA right now, but a public torrent is being worked. I'm gonna install this build on a VM, because I'm still having a lot of fun dual-booting W7 7601 and W8 7955
