HP Update utility checks for and downloads updates of your computer's firmware, or Basic Input/Output System (BIOS), software, and drivers. It can also help you update the security and functionality of your Windows Vista operating system.
HP Update was installed on notebook PCs that shipped with Vista and it is supplied with the installation of programs for HP printers and accessories. While it is helpful for locating drivers and accessories, it is recommended that HP Support Assistant is used on a scheduled basis to get updated drivers for all HP equipment. To learn more about how you can use HP Support Assistant to upgrade your drivers and improve your computer's performance, see HP Notebook PCs - Installing and Using HP Support Assistant.
