Install Windows 10 with retail disk. Bought OEM product key. How to activate?

Hi,

I've installed Windows 10 (Core) with a retail disk (by mistake), but the product key I've bought is OEM. Windows doesn't want to activate with that key.

Is there a way I can change the channel from 'Retail' to 'OEM' by modifying the registry or someting? Is there a way to activate with that key anyhow?

 

Transfer of retail windows product key. Will the OEM stay and be used again?

I thnk it was windows 7/8 Home OEM that was upgraded to windows 10 Home OEM. Then my brother gave me a product key that was bought on a box that looks like it's from microsoft I think that turned it in a Windows 10 pro. Can't really remember but when I checked my product key it says Licenced and retail.

 

Simrick's idea to enter a Win10 Pro retail key worked

Thank you guys. Note added under step 5 below.

Upgrade Windows 10 Home to Windows 10 Pro
