OSNews reports that Windows 7 Build 7025 has been leaked

Despite the success of the Windows 7 beta, which got leaked before it was officially released and had several deadline extensions, Microsoft isn't exactly sitting still. The beta build, with build number 7000, was built on December 12th, 2008, so that leaves enough room between then and now for several newer builds. One such build got leaked this weekend, and it contains some minor changes compared to the beta build.
