Hi,
I got a piece of paper containing my Windows 10 Pro OEM key, but suddenly, the OEM key did not WORK!
I previously activated a PC with a retail key, but never with a OEM key. The product key is HYMTN-XQ4VY-GTRD6-BQ9MQ-4GCC4. How I am supposed to activate my PC again! I tried retail Windows 7/8 keys that I own but they say it is in use on other hardware.
I am not buying another Windows 10 OEM product key again! Retail keys are fine, but not OEM keys.
The OEM key has to be manually activated. It is not pre installed.

Please don't purchase OEM keys as they are not sold by Microsoft.
OEM are preinstalled on computers and cannot be moved from one computer to another.
