I had to reformat my pc due to a bug caused by a win 10 preview. I did not realize my pc was Vista, so I\’ve been slowly upgrading my pc from one version to the other. I luckily found my windows 7 disc. I needed it to get windows 10 for free. After downloading through the website and stating that you can upgrade PC\’s with windows 7 through windows 8.1, it blocked me asking for a product key. I dont remember microsoft giving me a product key a couple months back when win 10 was released. What do I do from here?
If your product key for windows 7 is genuine and activated you should not need a windows 10 key to upgrade.. Time to call Microsoft..
