Custom user interface
User Configuration\Administrative Templates\System
Specifies an alternate user interface for Windows 2000.
The Explorer program (Explorer.exe) creates the familiar Windows interface, but you can use this policy to specify an alternate interface. If you enable this policy, the system starts the interface you specify instead of Explorer.exe.
To use this policy, copy your interface program to a network share or to your system drive. Then, enable this policy, and type the name of the interface program, including the file name extension, in the Shell name text box. If the interface program file is not located in a folder specified in the Path environment variable for your system, enter the fully qualified path to the file.
If you disable this policy or do not configure it, the policy is ignored and the system displays the Explorer interface.
To find the folders indicated by the Path environment variable, double-click System Properties in Control Panel, click the Advanced tab, click the Environment Variables button, and then, in the System variables box, click Path .
