Updating programs and drivers HP recommends that you up date your prog rams and drivers on a regular basis to the latest versions. Updates can resolve issues an d bring new features an d options to your compu ter. Technology i s always chan ging, and updating programs and d r ivers allows yo ur computer to run the late st technology available .

Using antivirus software Computer viruses can disable program s, utilities, or the operating system, or cause them to function abnormally. Antivirus software can detect most viruses, destroy them , and in most cases, repair any damage they h ave caused.
If you have instal led third-party software after yo u purchased your computer, regularly update the software. Software compani es provide software updates to their products to correct security problems and improve functionali ty of the software.
10 Using Setup Utility (BIOS) and System Diagnostics Setup Utility, or Basic In put/Output System (BIOS), controls co mmunication between all the input and output devices on the system (such as disk drives , display, keyboard, mous e, and printer).
BIOS version informa tion (also known as ROM date and System BIOS ) can be displayed by pressi ng fn + esc (if you are already in Windows) or by using Setu p Utility (BIOS).
NOTE: After a message on the screen rep orts a su ccessful installation, you can delete the downloaded file fro m your hard drive. Using System Diagnostics System Diag nostics allows you to run dia gnostic te sts to de termine if the compute r hardware is functioning properly.
11 Backing up, restoring, and recovering Your computer includes t ools provided by the operating system and HP to help you safeguard your information and re trieve it if ever needed.
