The Program and Features applet within the Windows Control Panel allows the user to manipulate software installed on the system in a number of ways; • Allows users to uninstall and change existing software packages, as well as indicating how much space individual programs take and how frequently they are used. • Allows users to manually install software from a CD-ROM or Floppy Disk, and install add-ons from Windows Update. • Allows users to change which Windows components are installed, via the Windows setup Wizard, which includes Internet Explorer, Windows Media Player and Windows Messenger. • Finally, it allows users to specify the default applications for certain tasks, via the 'set program access and defaults' wizard, such as internet browsers, media players and email programs and whether access to these programs is available.
