Licensing Questions

I recently bought the Speed Editor with a license for Resolve Studio. I understand that I am able to use this on 2 computers, but I'm curious to know how it works if I need to re-install Windows or I get a new computer, etc. - is there a way to transfer my license to the new computer and remove it from the old one? I'll need to update my Windows soon, which will involve wiping my primary drive. Will this "use up" 1 of the 2 license uses I have?
Thanks for any feedback or advice!
