Stopping Unneeded Startup Services
Along with the core operating system and programs that Windows XP runs when it starts, there is also a host of services involved. Many of these services are necessary for Windows XP to operate correctly. However, many of them are for features in Windows XP that you may not use at all. You can peruse the services and disable any service that you do not want to run. The fewer services that run, the more quickly Windows XP will boot.
Caution: Exercise caution when stopping services. If you do not know what a service does or are unsure of the ramifications of stopping the service, leave it alone. Some services are critical to Windows XP's operations, so make sure you understand what the service is before you disable it.
To reduce the number of services that start on bootup, you can access two different areas of Windows XP. The first is the System Configuration Utility. The Services tab shows you the services that start when the computer boots (see Figure 4-1).
You can stop a service from starting by simply clearing the check box next to the service and clicking OK. However, before you do so, there is another way to disable services that you may prefer because the interface gives you more information about the service in question.
Open Control Panel/Administrative ToolsServices or else select Start/Run, type services.msc, and click OK. Either way, you see the Services console (see Figure 4-2).
I prefer to use the Services console instead of the System Configuration Utility because it describes what the service does. Additionally, you can double-click a service and examine its properties.
Computer Browser: If your computer is not on a network, you don't need this service. If you are on a network, leave it alone.
Error Reporting and Event Log: You don't have to use these services but they can be very helpful, so I would leave them configured as automatic.
Help and Support: If you never use the Windows XP Help and Support Center (found on the Start menu), you can disable this service.
Indexing Service: Your computer keeps an index of files but if you rarely search for files, the
Windows Firewall/Internet Connection Sharing: If you do not use these features, you can disable them.
Messenger: This service sends alert messages on a local area network (it is not the same as Windows Messenger). If you are not on a network, you can disable this service.
Print Spooler: If you do not do any printing from the computer, you can disable this service. If you print, make sure you leave it as automatic.
Windows Image Acquisition: If you do not use scanners or digital cameras, you can disable this service.
You may have a number of other automatic services, depending on software and other configurations on your computer. So it's a good idea to look through the services and learn more about them. If you double-click a service, a Properties dialog box appears (see Figure 4-3).
Notice that on the General tab, you see a Startup Type drop-down menu. If you want to change an automatic service to manual, select Manual here and click OK. As a general rule, don't disable a service unless you are sure you will never use it. However, manual configuration allows the service to be started when you find it necessary, thus speeding up your boot time.
However, before you change a service to manual, look at the Dependencies tab (see Figure 4-4). This tab shows you which other services depend upon the service you are considering changing.
Keep in mind that services are necessary for the vast functionality you get with Windows XP. Change only those services that you understand and do not use. How you use your Windows XP computer should be the best guide in terms of optional startup services.
