    Factory OEM PC's like Dell, HP Acer etc embed a SLIC table in the BIOS. If you have the matching OEM-SLP install media it will activate against the SLIC table. That custom install media usually also has a $OEM$ folder in the sources folder. The OEM branding you see on the System screen plus other OEM stuff is in there. I build my own custom $OEM$ folders for each PC to add the OEM info during the install. I enter the product codes with a PID.txt file for my homebuilt desktop PC's. Windows 7 uses OA2.1 and Windows 8 uses OA3.0, OA standing for Oem Activation. Windows 8 won't read or use the Windows 7 BIOS SLIC table. It's embedded code is in a different part of the BIOS. In the XP days you'd get disks with the PC and those would be custom OEM disks with the OEM branding. If you use a normal store bought XP or Windows 7 DVD on an OEM PC it will not read the SLIC table and prompt for a product code. You won't get any of the custom branding either. Microsoft changed that for Windows 8. Now all DVD's ( even store bought Retail disks) look for the embedded code. You won't get the branding but at least it will read your code and activate automatically if you have an OEM embedded code in your BIOS.

    I get it now, so no made for Windows 7 PC or Laptop can use a Windows 8 Core version then?

    SLIC yah I forgot that arrangement of letters, thats what Odin uses, In that sense it is different than the new KMS hackracks.

    I think what MS wanted more than anything with 8.1 was to defeat some of these more used cracks, because 8.1 can totally block the executables from running.

    You can install 8 Core on a Windows 7 PC, you just do it the normal way and enter a product code during the installation. Yeah a lot of the changes made with OA3.0 are to block some of the common exploits.

    Then it is no longer a Core version really.

    ????? huh, There is Core and Pro, being OEM or Retail doesn't change any of the features available? Core is Core. Your tech support options are different but its the same installed OS.
