Microsoft claims it's selling Windows 7 at a clip of seven copies per second (that's more than 150 million copies since October 2009, according to the company's math) and it probably doesn't want anything to interfere with that rate--certainly nothing like rumors that the company's already sweeping the decks for Windows 8.

Yet those very rumors are circulating today, courtesy of a purportedly leaked slide deck posted June 26 on a Website called Microsoft Journal, run by one Francisco Martin Garcia, who bills himself as "Microsoft VIP Tester." According to the slide deck, internal discussions about Windows 8 are already well under way, with planned features such as a display that adapts to ambient light for maximum visibility, ultrafast boot times and using facial recognition for log-ins. Also mentioned are USB 3.0 and Bluetooth 3.0.

On June 28, the blog Microsoft Kitchen also posted some purported Windows 8 slides, which it said came courtesy of an Italian Windows site called "Windowsette." These slides include an image of a Mac-like "Windows 8 Prototype Machine," and reiterate the Microsoft Journal's slides' discussion of facial recognition log-in.

"Windows accounts could be connected to the cloud," reads one of the slides posted by Microsoft Kitchen, followed by the bullet point: "Roaming settings and preferences associated with a user between PCs and devices." That would certainly fit with Microsoft's oft-plugged "screens and a cloud" strategy, not to mention make it easier for a user to migrate from device to device within a household or office.
