I have no words to describe the mess Microsoft created in the font rendering in Windows 10.
Just look at this explorer window. Some elements like title bar and address bar have a grayscale antialiasing, the rest has cleartype enabled.
Ok, let's open ClearType Tuner and select a third option on a third page which is a grayscale cleartype.
And guess what, it's still the same! This tool has no effect at all on the cleartype's color settings.
Disabling cleartype is no option, as the text becomes a total mess.
