    SoftwareLicensingInternalCode.

    It's used by OEM pre-installations of any version of Vista.
    At this licensing model a special certificate has to be installed. Together with a royalty key it activates against the SLIC, not against a M$ server or via phone.
    This type of license is called SLP2.0 (SystemLockedPreinstallation) or OEM_SLP.

    A SLIC consists of a public key and a marker code, which are parts of a OEM SLIC bios. The SLIC table is called like a usual ACPI table.

    So Vista 'looks' for it. If it is present it says: "I'm activated."

    just a question again: if the SLIC in the bios is for home, would it install home?

    how do I know if SLIC is working?

    I have an oem DVD here that has 00141 at the end of the product key. when I updated the bios to something with SLIC and then installed vista, the product key is still the same.

    any ideas?

    thank you

    The SLIC works if you install Vista and the installation can be activated using the slmgr.vbs utility. Some SLIC can only activate certain type of Vista (for example, activate Home Premium but not Ultimate) while others are more broad.

    Well, System Properties should be able to tell you right? Right-click Computer on the desktop and select Properties.
