Disable ClearType (blurry fonts) in Internet Explorer 10 on windows 7

In IE10, full sub-pixel anti-aliasing is removed and what remains is greyscale anti-aliasing, although they still call it "ClearType".

This is by design, as described in ClearType takes a back seat for Windows 8 Metro.

This affects the Metro UI, Metro style apps including IE, as well as desktop IE, and nothing can be done to fix it. Font-rendering on Windows 8 is optimized rather for tablets and small laptops than for PC.

Unless Microsoft returns this option in the future to IE10, and if you cannot live with ClearType, then your only option at the moment is to to turn it off for the desktop and use another non-IE browser as the default browser.
