AutoRun LWMenu is a control menu that can launch applications, URLs, system commands, etc.
It’s not only portable itself, but acts as a portabilizer so the launched apps will become portable too. In fact, it can back up and restore whole registry values/folders/files of the programs it launches (or just use symlinks to run folders/files portably), including unique features like a simulator to test everything, kiosk mode where the menu must remain open, and auto button clicks.
