    good morning.
    here's my question: let's say I have a laptop with its own MS Windows product key; to install a clean version of the operating system, bypassing factory recovery dvd and use anyway the above-mentioned key, is necessary modding the bios and upgrading the SLIC?
    thanks

    I own an Acer Aspire E1 572G with native Windows 8.X (now upgraded to 10); I'd like to make an hardware upgrade installing 8GB ram memory and an SSD hard drive.
    so my question was if I needed modded bios to use an 8.X iso downloaded from MS official web repositories with my own product key pasted on the laptop, instead of using the factory recovery iso full of bloatware.
    can I easily check if I already have any SLIC? how, if yes?

    As LatinMcG has said, Slic was used for Windows 7, Vista & some Server OS.

    Windows 8 uses an MSDM Table in the bios with your injected product key.
    If you open an Admin Command Prompt (press Start+X, then A) you can retrieve your product key by typing:
    Code:
    wmic path softwarelicensingservice get OA3xOriginalProductKey
    The Windows 8.1 setup should auto read the key & allow you to install the matching Edition... So no need to enter the key anyway...

    i just ran into an hp with msdm missing.. bios update says model not compatible.
    lucky it boots mbr also.. im doing DAz on 7 to get Genuineticket.xml for 10 install.
    not bothering with missing msdm.

    edit: apparently the genuineticket tries to grab missing msdm and bypasses the 7 genuine.
