WPF font rendering was fixed in .NET 4 back in 2010.

IE10+ on Windows 8+, Office 2013+ on Windows 8+ and the Modern/Metro/Immersive environment on Windows 8+, on the other hand, are doomed to have poor font rendering thanks to their use of the Direct Manipulation APIs: http://blogs.msdn.com/b/oldnewthing/archive/2015/01/29/10589...

I doubt this will be fixed - the world is slowly moving towards high DPI screens where subpixel font smoothing isn't as important. For existing hardware, though, it stinks.

I don't notice it much in Office because the font sizes in use tend to be a bit larger. Whereas small fonts are much more common on the web, and the bad rendering is really noticeable.
