Despite rumors suggesting that Microsoft would release a beta version of Windows 8 at CES in January, the company has now laid those claims to rest by announcing that it will give people a chance to test the software out in February.
According to a forum thread on BetaArchive, a forum responsible for leaking Windows 8 builds in the past, there's a new Windows 8 build waiting to be leaked. The new build, allegedly with 7989.winmain.110421-1285.615974c7346f7374 as its build tag, seems to include small improvements when compared to previous builds, although the new tile-based user interface doesn't seem to be included, at least judging by the leaked screenshots.
