Note: To find out how much memory, also known as Random Access Memory (or RAM), your computer has, right-click My Computer and choose Properties General. A Windows XP system needs at least 256 MB of RAM to work properly. Better yet, get 512 MB, or more, if you can afford it.
A. Eliminating Needless Visual Effects

Right-click My Computer and choose Properties => Advanced.
The Advanced tab on the System Properties dialog box appears. You can also summon System Properties from the Run box or the command line; enter sysdm.cpl and then press Enter.

Under the Performance section, click Settings, and then select the Visual Effects tab.
The Performance Options dialog box appears, as shown in Figure

Choose the visual effects you want.
"Adjust for best performance" turns off all the visual effects listed. "Adjust for best appearance" has the opposite effect: it turns everything on. Selecting "Let Windows choose what's best for my computer" triggers, as you might guess, different choices on different computers. And to pick and choose individual effects yourself, choose "Custom," then decide which ones you want.
Note: Sometimes, turning off a service only affects your current computing session; other times the service stays off the next time you turn on your PC. If you want to ensure these changes are permanent
2. Services You Don't Need

1 At a command prompt or in the Run box type in services.msc and press Enter.
The Services window appears, as shown in Figure 11-2. This program lists all Windows XP services,tellsyou whether they're currently running, and lets you start or stop each one
