Moving to Chrome is not enough. Because Microsoft uses this ugly font rendering everywhere. Modern apps, Office, etc. Even the Windows desktop. On Windows 10, the desktop rightclick popup menus look the same.
High dpi displays are also has problems, because regular windows desktop applications cannot be upscaled properly.
Yes, I also will stay with win7, there are some issues win newer windows versions, which I cannot tolerate.
Desktop can be fixed: Control Panel > System Security > System > Advanced settings > Performance (Visual effects...) : click "Settings..." Uncheck "Smooth edges of screen fonts". Might need to sign out/sign in (sometimes double sign out/sign in - really) to get Windows Explorer and context menu without font smooth.
I use font substitution to replace Segoe UI with Tahoma, to avoid Segoe which looks ugly without smoothing.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]
"Segoe UI"="Tahoma"
Might need to set all variations of "Segoe UI..." to get what you want/need.
In my eyes HiDPI is just a waste of energy - but hey that is how progress works, isn't it ;-)
