Recently I've been getting a lot of crashes so I thought about doing a fresh install. Now, I've been backing up all my important files and got an USB ready and all that.

But when I was about to install it to the USB, I remembered that I don't know my Windows key as I just cloned my drive from my previous laptop to my new desktop with the Windows on it.

So my question is: Is it possible to do a fresh install (Windows 10 if that changes anything) without knowing your key? Assuming it would ask for it when I was about to install it
