Information about a Windows 8 build from November have recently been posted on the Internet. The build dates back to November 8, 2010 and has the build number 6.1.7900.0. The build number indicates that Windows 8 in its current phase is still using the kernel used in Windows 7. That’s a natural process and Microsoft will switch to a newer Kernel later in the development, likely to 6.2.

According to sources close to the development process Windows 8 has finished Milestone 1 and is currently in the Milestone 2 phase. It is projected that the operating system will enter Milestone 3 stage in the first half of 2011 and it is likely that the first beta will be released in the second half of the year 2011.
