Internet Explorer and Firefox users have criticized the font rendering under recent versions of Windows in the past. Some Firefox users for instance began to notice a difference after the Firefox 4 installation or upgrade. Internet Explorer users after the Internet Explorer 9 installation. Add-ons, extensions and tweaks were discovered that resolved the issues on most systems. Firefox users could for instance install the Anti-Aliasing Tuner to improve the font rendering in their browser, Internet Explorer users a dll wrapper.
Microsoft has acknowledged the issue under windows 7 or Windows Server 2008 R2. The company notes in the official Microsoft Support listing that "core fonts in Internet Explorer 9" may appear "blurred compared with the same text and fonts in Windows Internet Explorer 8".
The fonts showing those behaviors are Arial, Verdana and Tahoma all on regular font styles and font sizes of 8,9 and 10 points.
This issue is caused by different font rendering techniques:
By default, Internet Explorer 9 uses sub-pixel positioned ClearType to render text by using DirectWrite, whereas Internet Explorer 8 uses whole-pixel positioned ClearType to render text by using the Microsoft Windows graphics device interface (GDI).
Microsoft has released updates for all versions of Windows that Internet Explorer 9 is compatible with. This includes the client operating systems Windows Vista and Windows 7, as well as the server operating systems Windows Server 2008 and Windows Server 2008 R2.
All update downloads require a validation before they become available.
The Windows PC needs to be restarted after the update installation.
The Knowledge Base article lists additional information about the update and the changes that it makes to the system. Microsoft mentions Internet Explorer 9 explicitly in the article, other programs however may benefit from the updated fonts as well. (via)
