MUI will run on computers that are running Windows XP Professional, but not on computers running Windows XP Home Edition.

MUI is sold only through Microsoft Volume Licensing programs such as the Microsoft Open License Program (MOLP/Open), Select, and Enterprise agreement. You can request an OEM version of MUI, although MUI is not available through retail channels to ensure that customers have the English version of the operating system running on their computers before they install MUI.
