According to the latest StatCounter analytics, Windows 7 has finally surpassed the aging Windows XP in American usage share.
Microsoft announced in January that it had sold 300 million Windows 7 licenses and that the operating system was the fastest-selling in the company's history.
The company's failed Vista platform fell to 19.5 percent while Mac OS X (all iterations) moved up to 14.8 percent.
When moving the numbers internationally, XP is still the champ, at 46.8 percent, followed by Windows 7 at 31.5 percent.
