Windows 10: Cant activate windows 10 pro after upgrading MB, CPU, and Ram

Hey everyone


I recently upgraded my MB, CPU, and Ram and now cant activate windows 10 pro


I had Windows 10 home (Have the product key and USB) and upgraded to windows 10 pro through the "Settings" in windows 10, I dont have a product key from when i ungraded to windows 10 pro.


i see the last 5 characters of a product key for my pro key but it isnt the same as my Home key, and i dont have the full pro key to enter.


If i click "troubleshoot" i get a message saying "Troubleshooting has completed, Were weren't able to activate Windows on this device" then if i click "I recently changed hardware on the device" and click "this is the device that im using at the moment" and then activate. i just get "Unable to activate Windows, We cant reactivate Windows on this device. Try again later"


Since i dont have the Windows 10 pro code i cant use that to reactivate and using windows 10 home code i just get an error saying this key cant be used



Thank you for any replies/help in advance

:)
