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

Most users don’t need to change any of these features and 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

For more information on these applications or others, you can click each item to learn more about the program, which can help you determine which programs to remove
