Can't activate reinstalled windows 8

About a year ago I bought a dell inspiron 15r with windows 8 single language installed.Dell didn't send me a windows installation disk and I don't know my product key.I didn't like windows 8  back then and made a clean windows 7 installation and used it for a year.Recently I decided to reinstall windows 8.I found a windows 8 iso file and installed it via my usb stick.It supposed activate my windows 8 automatically but it didn't.During the installation it didn't ask my product key,I thought it was activated but it isn't.The question is can I find my windows 8 product key with my service tag.


The iso file I found is windows 8.1 single language,I think there is no problems there.

Microsoft made Windows 8.1 installation media reject Windows 8.0 product keys during installation but not during activation. The solution is to install with a generic product key and then obtain your product key using RW-Everything. You can then activate using change key. See here for more details:
