By default Windows Setup omits some accessory programs that Microsoft deemed inessential (mostly network and administration tools). If you feel otherwise, you can install them from the Windows CD. You also can remove optional Windows components if disk space is tight or you don't want them cluttering your All Programs menu.
To add or remove Windows components:
1. Choose Start > Control Panel > Add or Remove Programs > Add/Remove Windows Components.
2. In the Components list, check a box to install a component; uncheck a box to remove it (Figure 6.7 ).
3. Click Next.
4. If you're prompted for the Windows CD, insert it and continue.
