Microsoft signed off on the RTM build of Windows 8 earlier this month
. At the time, the build number for the RTM version was 9200.16384.win8_rtm.120725-1247. Now a known Windows news leak source has posted screenshots that show a build number that is even higher than the one that Microsoft officially approved.
The Russian website forum WZOR is the source of the screenshots, which allegedly show that the next build number for Windows 8 is 9200.20495.120814-1420. No other information about the build was revealed in the screenshots.
