What is U3Launcher?

The U3 Launchpad (LaunchU3.exe) is a Windows program manager that is preinstalled on every U3 smart drive. The U3 Launchpad automatically starts at insertion of a U3 enabled device. U3 was a joint venture between SanDisk and M-Systems producing a proprietary method of launching Windows applications from special USB flash drives. Flash drives adhering to the U3 specification are termed "U3 smart drives". U3 smart drives come preinstalled with the U3 Launchpad, which looks similar to the Windows OS start menu and controls program installation. Applications that comply with U3 specifications are allowed to write files or registry information to the host computer, but they must remove this information when the flash drive is ejected. Customizations and settings are instead stored with the application on the flash drive.


During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The primary executable is named _294823.exe. The setup package generally installs about 47 files and is usually about 701.5 KB (718,336 bytes).
