It was my foolishness that I have damaged the OEM key. One of my friends gave me a cracked designer software and after installing that software in my Surface Pro the Windows 8 product key has been changed. I resetted the surface to factory default setting then also I am not getting the Original Key and I am not able to Activate my Windows 8 pro.
I contacted Microsoft Support and they informed me that the OEM Key is pre-injected and they have no records of the Keys in their server or anymore.
I resetted many times to get the original key but that was a failure.
Please any body help me to recover my original key that will be great help.
Thanks in Advance
