Looks like we are dealing in millions again. Microsoft has had a record of sorts by selling over 150 million copies of Windows 7 since October 2009, that turns out to 7 copies every second since launch.
Windows 7 is one of the best operating system ever created by Microsoft. After the farce Microsoft created called Windows Vista, people have embraced Windows 7 with open hands.
In January Microsoft had said that Windows 7 is the Fastest Selling OS in its history, and the sales figures definitely show that it is indeed making Microsoft a lot of profits. Now hopefully Microsoft will also emulate the same success with the Windows Phone 7 and Microsoft Kinect platform.
