60M Windows 8 licenses have now been sold, Microsoft (MSFT) announces. That's up from the 40M the software giant had sold as of late November. Microsoft notes this figure includes "both upgrades and sales to OEMs for new devices" - the latter could include licenses being held as inventory by OEMs. Figures from Net Applications, NPD, and others have tempered hopes that Win. 8's revival would stoke a rebound in PC demand.
