Upgrading to the latest version of Windows typically requires Enterprises to do full line of business app compatibility testing with the latest version of Internet Explorer. What makes this a difficult task for most Enterprises is that they often do not know which of their catalog of internal line of business applications are critical and used by their employees. Often times this leads IT Pros to test all of their internal apps, even ones that may not be used, which can be a costly and time consuming process. In addition to testing, it can be difficult to mitigate compatibility issues without knowing more about how the application is built.
