interface
At least
Microsoft Windows 2000
Specifies an
alternate user interface for Windows 2000. The Explorer program
(%systemdrive%\program files\internet explorer\iExplorer.exe) creates the
familiar Windows interface, but you can use this setting to specify an
alternate interface. If you enable this setting, the system starts the
interface you specify instead of Explorer.exe. To use this setting, copy your
interface program to a network share or to your system drive. Then, enable this
setting, 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 setting or do
not configure it, the setting is ignored and the system displays the Explorer
interface. Tip: To find the folders indicated by the Path environment variable,
click System Properties in Control Panel, click the Advanced tab, click the
Environment Variables button, and then, in the System variables box, click
Path.
