A major online retailer is hawking Windows 8 a full fortnight before Microsoft plans to formally release the operating system.

Newegg, which caters to tech enthusiasts and hobbyists, features several versions of Windows 8 for sale on its website. It's selling both the 32-bit and 64-bit versions of Windows 8 professional for $139, and 32- and 64-bit versions of the standard edition for $99.
