Windows 7: 350 million licenses sold in 18 months
 

Eighteen months after Windows 7 was released, Microsoft is boasting that it has sold 350 million licenses of its flagship operating system. The platform's sales have barely slowed since the company last bragged about numbers; after 12 months, 240 million licenses had been shipped.

All a far cry from Windows Vista's market take-up. Though Windows Vista sold well—around 330 million Internet users two years after launch—its reception was lukewarm, and though users actually quite liked it, it failed to achieve acceptance in the essential corporate market.
