Windows 10: Windows License on re-installing

My PC is seriously messed up. Don't bother asking me the specifics-It's just too painful I can't even open my settings
So I have decided to nuke the hard drive and do a clean install. My question is: What happens to my license key? Do I have to buy another one?
I did not buy a license from Microsoft as I used a third-party. I think I have a digital license but I can't exactly tell.

re-installing windows on laptop

If your disc is pro and laptop has the pro license as well then just use that disc and install it. If laptop has other license (home) then you need to unlock your windows 7 disc. Copy content of that dvd, remove ei.cfg file in the sources folder, and then use oscdimg to make a bootable iso and then just burn it on dvd or make a bootable usb. You can even add latest drivers and updates to that dvd/usb. Here's how and here.
