Hi everybody. I got a computer last christmas (2012) and it was pre-installed with windows 8.
As something happened to my computer (all metro apps stop working, inclusive settings, scince it's a metro app) I decided to make a full system restore. When I finally were able to find how (Without using settings) i did it.
Now I have a Clean computer with windows 8 but it says I have not registered windows 8! As I'm pretty used to computers, I looked for the serial number under my computer. I thought I found it (Teh number after S/N) but it wasn't that. (Some of the numbers were not usable in a activation key, such as L and W) As I go into computer info, i see a code which looks like this: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX, but then I get to the wierd part. "This Product key is already used on Another computer, Try with Another key or try again. And when I try again 0 can't be used...
Can somebody please help me? I can't understand why windows need to be reactivated after a full system restore on a windows 8 pre-installed computer...
