I bought a new laptop last year, a Dell Inspiron 15 5577 (7th generation i5) that is sold as a "gaming" laptop with an M.2 SSD (fast). I wanted it for on-site recordings. I tried tweaking it for audio recording including removing Dell added software and even some other software and settings but could never get it clean and had Latency Mon issues and some dropouts. I restored the original Dell factory image and installed a second SSD. I only installed Win 10 and minimum drivers on the new SSD, and Sonar, nothing else and it works great for recording. I still have the original Dell install if I want to use it for general PC work. Its set up as dual boot for whatever use I want.
Did you ever check that out with
Autoruns? (that is a nice "msconfig" utility that will show you all the things Win10 can hide from you). One thing I have noticed with Win10, is that they make it easier to hide entries within the machine, so stupid things like NVIDIA's telemetry data becomes an issue, etc. "Simple" maintenance doesn't go as far as it used to, and "settings" getting reset after major updates is not cool.
As far as the OP, I do not see many earth-shattering improvements that would get a Win7 user excited. If you step from Win7 Ultimate (or better) to Win10 Pro (or below) you actually lose safety features (they require Win10 Enterprise, or Win10 Educational, to retain).
