Lenovo OEM DVD .ISO

In somewhat major blow to anti-piracy efforts Microsoft Windows 7 Ultimate activation crack is now available before the official release of the software, the OEM SLP Master Product Key based activation crack completely bypasses the Windows Genuine Advantage validation allowing users a fully functional unlocked copy of the operating-system, the crack was made possible by extracting the OEM certificate and key from .wim files contained in leaked Windows 7 Ultimate OEM DVD ISO from Lenovo.

Microsoft makes use of SLP (system-Locked Preinstallation) for pre-activating Windows meant for volume licensing by OEM's like Lenovo and Dell, Windows 7 makes use of OEMID (identified by BIOS SLIC table) to identify OEM computers for pre-activation, crackers have now came up with automated utilities (as shown above) which make use of Lenovo's OEM key and OEMID to fake identification as an OEM system allowing Windows 7 Activation.
