由于IE8浏览器在渲染技术和标准支持方面变化较大，导致不少现有网站都无法与之兼容，也就是在新版浏览器里不能完全正常显示。

为此，微软在IE8里加入了兼容浏览模式，根据内置清单为不同的网站自动选择合适的渲染模式，并且这份清单会定期更新，增加新发现的不兼容网站、删除已经改进的网站。

Windows Vista IE8不兼容清单：
http://download.microsoft.com/download/4/6/C/46CC21F9-172A-4F9E-A872-CA0A015421C8/IE8-Windows6.0-KB961813-x86.msu

Windows XP IE8不兼容清单：
http://download.microsoft.com/download/F/4/0/F40AB8FE-9F68-4D0B-8A9E-06B000540066/IE8-WindowsXP-KB961813-x86-CHS.exe

下边就是目前已知的与IE8不完全兼容的主要网站清单，共计大约2400个，排在前列的就是多家国内大型网站(驱动之家也暂时在列)，最有趣是微软自家官方网站(microsoft.com)也位列其中。注意这份名单是从微软XML Schema中得来的，没有按照字母顺序排列。
