Windows 10: With the mainboard/CPU change Windows license disappeared?

Hello everyone, I changed my mainboard/RAM/CPU and now my PC thinks I should activate Windows. Unfortunately I don't have the key (was with my PC). How do I get it activated? Best without my old mainboard again

upgrading mainboard and CPU

This question is probably asked before, but I cannot find it.

I want to upgrade the mainboard and CPU and wonder if I can activate the Windows 10, which I used with the old mainboard, on the new mainboard/CPU?

I should add that the the Windows 10 running on the old motherboard was a free upgrade from a retail Windows 7 Home Premium. I still have the original Win 7 DVD with the product key.

 

Windows 10 Pro activation failed - Recently changed mainboard+cpu

So my old mainboard which I bought 11 years ago and houses an AMD Phenom X2 CPU broke down last week, and since I can no longer find a cheap mainboard that supports that CPU, I decided to "upgrade" to a new mainboard and switch to Intel i3 cpu, at the same
time installing new pieces of DDR4 RAM too.

However, my windows 10 pro is installed on my Samsung SSD and it works just fine with the new hardware, so I can go straight in into Windows, and later I discovered that my windows activation status has changed to 'not activated'.

After a lot of troubleshooting and reading several articles, I came to realise that I may not have linked my previous activation to my microsoft account (I have a hotmail account).

So the trouble now is I cannot get my windows activated using that product key I bought from last time (which I purchased in either 2017 or 2018, I don't remember).

What should I do?

You will have to buy windows license if you change the motherboard, unless you made the computer originally in the first place, or bought a license key.
