I often run into issues where newer versions of IE will not work with some of the websites that our users have to access. The sites only work with IE and most only work correctly with IE8, and no amount of compatibility mode or tweaked setting will give you full functionality when trying to use newer versions. This becomes a real pain when rolling out new computers that come with IE9 and now IE10 preinstalled. You can find some info online and a lot of arguments on the best way to “roll back” to IE8. After ALOT of searching and trial and error, I finally found a Microsoft Fix it that will do it for you fast and easy. It is Microsoft Fix it 50778. Just run it and be done with it.
