You'd be forgiven for thinking that the world's now completely and utterly infatuated with Windows 8, but its little sister still appears to be doing just fine. Microsoft's Steve Guggenheimer announced at Computex that since selling 525 million Windows 7 licenses back in January, it's now hit the 600 million mark. Guggenheimer reckons that Windows 8 will be "the biggest launch time in Microsoft's history." And we're unlikely to argue -- the company does like to put on a show.

Updated: To celebrate, Microsoft's cooked up a video of the hardware journey of Windows 7. It's right after the break.
