The product key is for an old computer, not your new build. You won't be able to use it on the latest system.

I upgraded my old machine to Windows 10 Home and wonder if I can still use the product key from before.
It's secured within the device and won't work on a fresh computer. You'll need to buy it separately.
Sure, I can try for a 30-day test period. What would you like to do?
I frequently work on similar projects and haven't always gotten the results I hoped for. Not an OEM version. However, as Czex mentioned, it's worth trying.
If it doesn't work, you can keep using the PC, but expect frequent notifications warning about activation issues.
Windows can be set up without going through the activation process, though it will lack some advanced features.
