In Windows, Control Panel>System>Advanced and IIRC there is an Environment variables... button. You click it and this opens a dialog that lets you set/edit environment variables. You can the add a "user" variable with name GIMP2_DIRECTORY and value C:/Users/Administrator/AppData/Roaming.
This said, running Windows as "Administrator" is not a good idea.
