John, there is only a service pack 1 for Windows 7, so you can't go higher. That being said, Windows 7 goes end-of-life in January 2020, after which there will be no more security patches (feature patches ended a while back). I'm in the same boat, as I run Windows 7 on my laptop (didn't go to Windows 10 on it because HP didn't provide proper drivers for either Windows 8 or 10). I can run 10 (and probably will come January), but only get a generic video driver and HDMI doesn't work for when I try to connect my laptop to a TV, nor does the fingerprint reader. But I digress.

Just be aware that come January you may have security concerns with your computer(s).
