There is a Microsoft Documentation page about ClearType that claims the registry values are under "HKCU\Software\Microsoft\Avalon.Graphics\display names"
source: Microsoft doc page
Our Windows 10 machines have no registry folder at all called "Avalon.Graphics" or anything like it. Where are the keys that control ClearType settings?
For informational purposes, I have already set keys in a different location (HKCU\Control Panel\Desktop) to FontSmoothing = 2 (enabled), FontSmoothingGamma = 1200; but all the font on the system is still pixelated. Something has changed and this key is not the only value needed anymore.
