I upgraded my one-year old Dell Inspiron 7537 laptop from Windows 8.1 to Windows 10. All went very well. Win10 is a nice improvement and all of my apps, programs, and drivers run fine. The only downside - Win10 boots slower than my Win8.1 installation, probably about 50% slower. I have the absolute minimum number of apps/programs loading at startup. Would a clean install of Win10 help this issue?
