WZOR has leaked yet another set of builds, having acquired the x86 (no x64 version) of Windows 7 build 7231 and the x64 version (no x86 version) of Windows 7 Build 7232. Unfortunately, no image files were leaked, just VHDs (Virtual Hard Disk), so these leaks are slightly more difficult to install than a normal ISO. Nonetheless, both have been leaked and have spread to various P2P networks.
