    I just purchased a Samsung NP350 Laptop with Windows 8 preinstalled.

    I am attempting to downgrade to Windows 7.

    Slic tools report a Slic 2.1 key, but cannot activate Windows 7.

    Is the only method to do OEM activation to mod the EFI bios?

    Thanks for the quick reply. I experimented with daz loader. It was able to get Win 7 activated if:

    1) BIOS was configured to emulate BIOS (CSM mode instead of EFI)
    2) Partitioning is done with MBR (instead of GUID Partition Table or GPT)

    This may be a valid solution for some people. But I have chosen not to go that route. One of the advantages of EFI with GPT is faster boot times. I dont want to give that up.

    If I could use the existing SLIC string I would, or if there was a way to rewrite it that would work too. But I dont want to use a loader.

    I am sure there will be a lot more people wanting to do this in the future as the computers being sold are all moving to EFI.

    Has anyone been able to do this yet?

    What error do you get when you attempt to use the product key that matches your slic and install the .xrm-ms license file?

    It said the product key was invalid. But the key is fine. The problem is that Win7 is looking for Slic 2.1, and the bios has the new Windows 8 Slic 3.

    Was the correct certificate instsalled (xrm-ms or similar file) ? I don't think you can activate without such certificate. You would need the cert for samsung.

    Because i dont need a touchscreen interface on a laptop with no touchscreen. If microsoft was not forcing this by removing the aero interface and other essential parts of windows I would go with Windows 8. I think you will see that Microsoft has made a big mistake here. The problems they had getting people to switch to vista will seem small by comparison.

    You could use Win7 pro or enterprise with mini kms and keep all uefi and gpt stuff. A least I think so.
