There have been a few reports as of late claiming that Windows 8 has been underperforming sales-wise, but Microsoft’s latest announcement makes it clear that it is anything but. Tami Reller, one of the two women now leading the Windows group at Microsoft, took the stage at the Credit Suisse 2012 Annual Technology Conference to reveal that OEMs, enterprises, and individuals have already purchased 40 million Windows 8 licenses since the OS launched one month ago. “The journey is just beginning,” said Reller, ”but I am pleased to announce today that we have sold 40 million Windows 8 licenses so far.”

Sales of Windows 8 are just as strong as Windows 7 – if not better - and upgrades of the new OS have actually outpaced its predecessor, indicating that people are actually taking the time to upgrade their old PCs. Windows 7, by comparison, sold 60 million licenses during its first two months on the market. The Windows Store also surpassed 20,000 apps over Thanksgiving, doubling in just one month the number of apps that have been added to the Mac App Store over the last 23 months.
