If you downgrade from Windows 10 to Windows 7, you'll be missing a lot of things. One is Cortana the digital assistant, Cortana can be of assistance in a flash. Two, you'll also miss a lot apps that can run on smartphones and tablets in smaller versions that also runs on desktop PC's through Windows 10. On Windows 7 you are limited to standard applications available on all Windows operating systems.
