Can't activate windows after a motherboard + CPU change

Hey, I recently upgraded my PC's motherboard and CPU, now windows is telling me to activate windows (i bought a key somewhere between late 2017 to early 2018), whenever i try to troubleshoot in the settings, all i can select is my OLD motherboard device
(windows seems to see it and my new motherboard as seperate devices) as the device i'm currently using, i cannot select my new motherboard so i always get told i cannot activate windows.

I have tried downloading a program that is meant to show me my product key (produkey), yet when i try to enter this in settings, i get an error (0x803fa067).

Am i screwed? Do i need to buy a new key?

 

Issue Activating Windows After Changing Motherboard and CPU

I recently upgraded my CPU and Motherboard, but after doing so my Windows 10 Pro is no longer activated. I haven't done anything to my hard drive, other than hooking it up to the new CPU and Motherboard. I've tried re-entering my Windows Product Key, but
it gives me an error.

We can't activate Windows on this device because you don't have a valid digital license or product key. If you think you do have a valid license or key, select Troubleshoot below. Error code: 0xC004C003.

I've also tried using the troubleshoot tool in the Settings --> Update & Security --> Activation section. Clicking "I changed hardware on this device recently" doesn't display this computer, just another laptop I have. Clicking "See other devices linked
to your Microsoft account" shows my wife's laptop, but still doesn't display this computer.

Essentially, it keeps telling me I need to buy another copy of Windows, but considering I already had Windows activated before the motherboard and CPU swap, there should be absolutely no reason that I need to buy another copy.

What do I need to do to get my Windows activated?

 

new motherbaord and cpu, windows activation

so basically my pc is 6 years old, i recently had to replace my cpu and motherboard and of course that means i have re activate windows, but i dont have the cd key from 6 (nearly 7) years ago. Do i seriously have to buy a new copy of windows?
