    Because there is no legal way to do this perhaps?

    That was my thought as well, but was just curious to see.

    Totally legit way guys - and here it is:

    How to Get Windows 8 to clean install:

    Get RWeverything @ rweverything.com

    use rweverything to check your ACPI -> MSDM to find out what your key is

    Replace or upgrade hard drive.

    Clean Install with the SAME version that your OEM machine was installed with.

    Once installed and into the OS - load an administrator CMD and use the command: slmgr /ipk

    [Product Key] to enter in the key you found using rweverything.

    Once I did this - windows 8 automatically activated (must have checked the bios using

    slp3.0?) - there was no need to activate over the internet!

    ALSO - You could technically replace the hard drive first, and after the clean install run

    rweverything (in the case you get a system with a dead hard drive). Just make sure that

    you install the version that came with the system!

    Sorry, but there's no need to go through all that, but thank you for sharing.

    On new OEM Windows 8 computers, the OEM product key is embedded in the BIOS/UEFI firmware now. It will auto insert and activate Windows 8 when installed.

    Yeah, I read that whole forum you posted as part of my research.

    The clean install using a generic (non oem branded) win8 disk didn't auto activate when a clean install of win8 was put on.

    Note: The key that was found with rweverything IS the key in the BIOS.... the one that is checked.

    So once I entered THAT key into the clean install of win 8 - it auto activated.

    Should this be made a sticky? I would have loved to have found this info right away without hours of searching.

    Unfortunately, we can't sticky everything.
