Development of Windows 8 started before the general availability of Windows 7.
A Microsoft employee stated in his blog that Windows 8 will have the NT version number 7.0 and that the OS won't be shipped in a x86 version, but only as x64. However, the April 2011 leaks and PR from Microsoft indicated that the 32-bit Windows would continue and that the Windows 8 kernel version would be 6.2.
Steve Ballmer calls Windows 8 his "riskiest product bet" due to the high success of Windows 7.
At the CES 2011 in January 2011, a computer with an ARM processor was pictured running the "Windows 8" build 6.2.7867 showing that the kernel version had only changed to 6.2, most likely to keep compatibility with old software. It was determined to be an M2 build.
Four builds of Windows 8 in its early Milestone stages have been leaked: 6.1.7850 (M1), 6.2.7927 (M2), 6.2.7955 (M2), 6.2.7959 (Post-M2/Pre-M3), and 6.2.7989 (M3). Rumors show that because of the leaks of 7850, 7955, and 7959, two Microsoft employees were terminated due to leaking confidential software.
