2 “How-To”
2.1 Auto Installation Application
Dell highly recommends Dell Command | Update application (DCU) to automate the
installation of BIOS, firmware, driver and critical updates specific to your system. The application is
available to download on Dell Support Website Driver & Downloads page. Pick your system type
from the list or enter the service tag of your system to get the right version for your computer.
The DCU is supported on Precision, XPS and Latitude notebooks. The Dell Command | Update
tool allows you to keep your system up to date without you having to know every driver or
update needed. It will automatically interrogate your system and compare it to the available
updates on dell.com/support for your specific system.
