3. Turn off programs that run in the background.
NOTE: When the computer is turned on, a software group called the
Terminate and Stay Resident (TSR) programs automatically loads. These
programs activate some of the computer utilities, such as the anti-virus
software, but are not required for the computer to function. Occasionally,
TSR's prevent the HP software from loading so that it does not install properly.
In Windows Vista, Windows XP, and Windows 2000, use the MSCONFIG
utility to prevent TSR programs and services from starting up.
