"Windows Blue, or Windows 8.1 as it will potentially be called, was recently leaked. We couldn't help ourselves, and installed one of the leaked versions in a virtual environment so we could try it out. On the following pages we'll give you an impression of this significant update of Windows 8, build version 9364. Windows Blue is an early version, so it's perfectly possible that things you see here will not appear in the final release.
While this is an early build, it still feels more thought-through than the current official version of Windows 8. At the same time, it doesn't do anything to bridge the gap between Windows 7/Vista/XP and the new environment, it remains a big transition."
