I have a version of Windows 7 that contains Windows XP. How do I turn off the XP Mode?
By default, Windows 7 does not innately include Windows XP. It may be possible that you have either a dual boot environment with Microsoft Windows XP Home / Microsoft Windows XP Professional or a virtual solution most commonly referred to as Windows XP Mode with Virtual PC.
Select versions of Windows 7 (Professional, Enterprise, and Ultimate) do allow the installation of XP Mode and Virtual PC if one wishes to run an incompatible application (for example) within a virtualized environment of Windows XP Professional. XP Mode, as well as Virtual PC, does need to be downloaded, installed and configured to run properly.
