Windows Control Panel 113 The Remove function is usually the best way to get rid of programs you no longer need. Although it's possible just to drag a program's files from your hard drive into the Recycle Bin and delete them, that's really not a good idea. Programs don't just occupy space on your drive. They also put code into a special file called the Windows Registry and they sometimes put files or code in other places as well. If you don't use Remove Programs, you can't be sure that all vestiges of the program are gone. And the leftover bits could slow down your PC or make it work erratically. Fortunately, removing a program with this Control Panel item is pretty straightforward. Click the Add/ Remove Program icon, select the program you want to remove and click the Remove button. Win- dows will ask if you're sure and if you click Yes the program will be gone for good. Unlike deleting files there is no undelete feature. The only way to get the program back is either to reinstall it or to do a System Restore (see Chapter 39).

In the Sounds, Speech, and Audio Devices area of the control panel, you can control many aspects of your PC's sound, from the volume to the default playback and recording devices. (You shouldn't have to mess with this last one, unless there is a problem with your sound system. If that's the case, seek help from an experienced user.) Most PC speakers have a control that lets you adjust the volume, but you can also check or change
