Microsoft has sold 40 million Windows 8 licenses in the month since launch on October 26, according to one of the new co-heads of the Windows unit.

Reller was named as one of two executives to run the Windows unit after president Steven Sinofsky unexpectedly left two weeks ago. Julie Larson-Green heads the engineering side of Windows.
