How to re-install windows without an install disc or lisence code

[Saltirezz]

So I want to upgrade my cpu which means I'll need a new motherboard (mine is fm2+) but I just found out that I'll need to re-install windows ect, but I don't have the install disc or a license code so how do I do it? Will I just need to get windows 10 and put it on a usb stick? Plus could someone explain how I do it all

Thanks

How to do a CLEAN installation of Windows 10

As for the product key, unless your current Windows license is for Windows 10 and it's attached to your Microsoft account and not your hardware, you will need to purchase a new license (you can run Windows 10 without activation indefinitely).
