Maybe stick with Windows 8 to start with and install Start8, StartisBack or Classic Shell to get the old Start Menu back if that is what bothers you.
If you still don't like it (which I could understand as there are differences which aren't everyone's' cup of tea, despite what fanboys would have you believe) then yes, Windows 7 will operate fine.
