Microsoft just announced word today that Windows 7 is officially Microsoft's fastest selling operating system... ever. How do we know this? Today it hit the 100 million license mark, which means it was installed 100 million times worldwide, which means (hopefully) it was sold 100 million times.

This also means that one in ten of every single PC in the world is currently running Windows 7, myself representing one of those PCs. Windows 7 came out just six months ago, and already it has proven itself to be a tremendous operating system for both home users and enterprises.
