Ok, and in my case I installed / Activated Windows 7 via a loader. Now my main question is howto remove that part out of the SLIC? I recently upgraded my Bios with a newer version but that didnt clear out the SLIC information.
The loader does not touch the bios. It loads the slic info to memory. Bios update will (should) not affect the loader. You need to uninstall the loader. Depending on which you used, makes a difference on how to uninstall it. You may have to repair the install also.
The only time the bios are gone into (written to) is if they are suitably updated which it would appear you have not done - you have just used loaders etc. There will be no problems installing any so called OEM's that you may buy in a shop!
If you have a loader installed, the information you are seeing is the one injected by the loader in the memory and it is not your real bios. Uninstall the loader and run SLIC Toolkit to see the real BIOS. P.S.: two hacks together is not a good deal...
