Upgraded to Pro for Hyper-V, issues with duplicative ownership

Hi everyone,

I purchased Windows 10 Pro upgrade from Home edition so I can have access to Hyper-V to develop with Docker. I know; I could've just made a virtual Linux machine or installed a Linux OS, but I nonetheless decided to stick with my base Windows OS because I thought it'd be convenient at the time. Basically this is what happened:

1. I purchased an upgrade to Pro for $99
2. For some reason I ran into an error in the activation settings. I forgot what the error was, but I was having trouble getting my upgrade activated.
3. In my poor judgment, I instead searched for a Pro product key online and used that to activate.
4. So now, I'm stuck with my Pro edition but still unable to use Hyper-V and other Pro features (it fails to update on restart likely due to duplicative ownership issues with the key).

Is there any way to fix this or anyone I can contact? MS's default online support was not very helpful.

Thanks.
