Tami Reller, the Chief Marketing and Financial Officer for Windows announced the tally during her appearance at the Credit Suisse Annual Tech Conference on November 27.
Microsoft had not released any sales figures for Windows 8 other than saying the company sold 4 million upgrade licenses of the operating system to those with previous versions of Windows during the first three days it was available. Microsoft launched Windows 8 commercially on October 26.
How does this compare to Windows 7 sales? Microsoft said it had sold 60 million Windows 7 licenses from the end of October 2009, its launch date, to the end of January 2010 December 2009. So that's 60 million Windows 7 licenses sold in two months. So far, Microsoft has sold 40 million licenses of Windows 8 in one month.Microsoft Sells 40 Million Windows 8 Licences [zdnet.com]
