Select the programs that you would like to disable from starting up
each time you start your PC.
Here are some of the most common unnecessary programs that you
may want to disable:
• qttask.exe - QuickTime Icon
This is Apple’s Quick Time Tray Icon, as shown in
Figure 4-17, which lets you start Quick Time from the
System Tray.
This unnecessary program uses as much as 750KB of
memory.
Even if disabled, you can still start Quick Time from its
Start menu icon or by clicking an associated file such
as .MOV.
• realsched.exe - RealPlayer
This is a scheduler for some generally unneeded functions,
such as occasionally checking to make sure that RealPlayer
“owns” certain media types.

• realplay.exe - RealPlayer
This is RealPlayer’s system tray icon (called StartCenter),
which runs when Windows starts to preload some
RealPlayer components and provides a tray icon to access
RealPlayer.
However, this application also uses up valuable system
resources.
Even if disabled, you can still start RealPlayer from its
Start menu icon or by clicking an associated file such as
.MP3.
• hkcmd.exe - Intel Hotkeys
This is part of the drivers for boards with Intel 81x graph-
ics chips, and allows you to define hotkey combinations to
change video resolutions.
This is not something that most users do often, and it can
be done through Control Panel (Intel Graphics icon) or
Desktop Properties pretty quickly.
It’s recommend to stop this task to save resources and pre-
vent accidental use of the hotkey feature.

• soundman.exe - Realtek Sound Manager
This application lets you manage and control some of the
esoteric features of the Realtek sound chip.

can safely disable this program.You can always use the stan-
dard Windows volume control to change the sound volume.
• waol.exe - America Online
This is the main AOL executable; however, it does not
need to start during Windows boot.
You can always start America Online as needed, via its
Start menu entry or desktop icon.
