No, you don't necessarily require a Windows 10 product key. Many users can install and use the software without one.

I previously used Windows 8.1, received a suggestion to upgrade to Windows 10, and it functioned well. Now I need to revert to Windows 8.1 for some reasons and am considering installing Windows 10 again. Will Windows recognize my hardware automatically or do I need a product key?
Comic is correct, you should be in good shape and Windows 10 should automatically recognize your key.
This means you won't need to buy a new Windows since you already have one. It seems your budget has grown.
