Documents from HP revealed earlier this year that Microsoft may be preparing to scale back its plethora of Windows 8 editions, and leaked information on the company's latest internal builds appears to confirm at least one SKU. Winunleaked posted several screenshots of a post-beta version of Windows 8 today, documenting a "Windows 8 Pro" edition that includes Windows To Go and an option, through Windows Anytime Upgrade, to add extra features with a "new edition of Windows" — indicating that the Professional edition might not be the top SKU in Microsoft's plans.

Microsoft's Windows 8 Consumer Preview included references to a "Professional Plus" Windows 8 edition, along with the traditional Starter, Home Basic, Professional, Enterprise, and Ultimate editions. Microsoft is staying mum on its SKU plans for Windows 8, but a number of Windows watchers have called for the company to simplify its offerings when the operating system goes on sale later this year.
