Replacing failed motherboard

[ineedthatspam]

I bought a prebuilt PC a couple years ago and the motherboard recently died. Though I have changed many of the components over the years I have never had to replace the hard drives or the motherboard. The motherboard is an ipmmb-fm (formosa) If I replace the motherboard with the exact same model will I still need to buy a new key for Windows 10?

What are your specs?

If you have the original key which you used to install Windows, then all you need to do is input that key again.
