I found a way to get your Windows 10 key after upgrading because ive read reports of alot of people doing clean installs, and then have activation issues afterwards
you gotta download a program called " Produkey"
download here

http://www.nirsoft.net/utils/produkey-x64.zipI reformatted earlier today and used the Key this product gave me and it worked perfectly with no issues, and my windows is now activated.
When you go to install windows it will ask for a key just enter the one that was given to you by this software, and it will work.
I think this thread should be stickied
