All my Windows 10 upgrades have improved performance, so far (touching wood here, throwing salt etc). You might get an improvement with the new version due on or after August 2, but if not, it's worth trying a clean installation.... > Windows 7 works worse than 10 on my laptop, but that's because there are no drivers directly written for 7, so it BSODs a lot You can usually run the new OS on the old hardware, but not necessarily the other way round. Today's hardware is being designed for Windows 10 and has probably never been tested with Windows 7 (unless it's a business PC from Dell or HP).
