"The simpliest way to do it: In windows search type "edit group policy" Now we search for "custom user interface" it is under User Configuration\Administrative Templates\System. Now you have chose enable and under options to write the path for the program we want to start up instead of explorer, for example c:/launch box/bigbox.exe. Perfect way for an arcade cabinet. To reopen explorer again exit bigbox and press alt+ctr+del and open task manager, new task and write explorer.exe. Back to normal windows."
