If you still have your installation media, or, at the very least, your old license key, you should be able to reinstall Windows 10 without having to purchase a new copy. However, if you have neither of those, you will likely have to purchase a new license for the new board since Microsoft sees that as a "new system".

For windows home you would need to re-buy it, especially if it's a brand pc (hp, gateway, lenovo...)
One thing for sure it will not reactivate online and you will need to call microsoft
As for windows 10 pro, you should have no issues.

What OS is it?
Assuming Windows 10, probably not.
Read and do this before you change any parts:

Where did this OS come from?
