It seems that the first Windows 8 build has leaked, and from what we can tell, this leak does indeed appear to be verified as legit. This is a very early non-complete version of the newest version of Windows, and it does appear to have a very Windows 7 feel to it. Why would this be? Because in early versions of updates to Windows, the big changes come in what's called "Milestone 3," while this leaked release is definitely along the lines of "Milestone 1." Have a peek at this sneaky leaky and decide for yourself if it's worth diving into, or if it should still be left in the developing pit for a few more months.
You'll more than likely be able to find this "Milestone 1 Build 7850" of Windows 8 in all the usual FTP and torrent sites, but beware - this is a fresh breeding ground for viruses and hacks that'll lead the devil right into the heart of your PC. That said, why don't you just have a quick peek here instead and go ahead and leave it alone? Sounds great!
Build leak: Windows 8 Build 7850 Milestone 1 Build

Some new features included in this early unofficial release are as listed here: Windows App Marketplace (check this out [here]), SmartScreen Security Filter, Aero Auto-Colorization (Auto color-changing theme colors, and more customization options), the ability to mount ISOs, and a Built-in AppX PDF Reader and IE9 Tile-based Metro UI. Take a peek at some screenshots below.
And again, we're not providing links to the torrents or other downloads of this build because it's a: insecure, and b: not exactly legal to have. Not to mention that it's so very incomplete that it might have your computer running laps until it dies. SO rejoice that we're a step closer to a final build, and be careful if you try to see it early!
