Microsoft has finally updated the core Windows fonts that will improve Internet Explorer font rendering. This issue dates back to the release of Internet Explorer 9. Internet Explorer 8 used whole-pixel positioned ClearType to render text by using the Microsoft Windows graphics device interface (GDI). But Internet Explorer 9 uses sub-pixel positioned ClearType to render text by using DirectWrite which results in blurred and not so smooth fonts in Internet Explorer.
Several fixes were suggested by users but finally Microsoft has come up with a permanent solution. Now you can update your core Windows fonts in order to fix this issue. You can download the fonts according to your Operating System installed. I am giving the download links of all the versions supported.
