Reinstall OEM windows 8.1 pro 64bit system

I have a XPS 14 L421X

My computer came with an OEM key preinstalled windows 8.1 pro 64-bit. I had issues with the keyboard so the dell support changed out my keyboard and motherboard the second or third keyboard switch I had, a service that dell ordered and paid for. When I upgraded to windows 10 recently the system crashed impossible to boot. So I plugged in my recovery USB (sent from dell for previously) and attempted a systems recovery, no luck. It asks for windows key which I shouldn’t do when I have an OEM and the same version as previously.

I spoke on the phone with the support that just is saying that my warranty has expired for the hardware that was installed. It’s supposedly 3 months.

I spoke with Microsoft that can’t help me cause of the OEM and refers to the retailer, dell.

Now I have researched the problem on the web. I booted into windows using a generic key. I wish to activate my key, I did pay for the computer to have windows 8.1 pro.

I downloaded lots of programs and read a howl lot of articles. I have tried the program “rw everything” but have no MSDN. I tried the Internet explorer key (IE key) it seems to be the wrong key for activation.

Below is a diag report, CLEARLY A DELL LICENSING!!

But for some reason it seems to be a Windows 7 OME maker on the motherboard. What the h***? Some recovery tool told me that I had a “Win starter retail” original key, that doesn’t seem to work for activating with windows, same as IE key.

How can I reinstall my OS and activate my real key? Please help me!!!
