The IIS 7 Feature Set

Table-1 describes all of the features that are installed by default. In addition, it outlines recommended features for modern web sites running IIS 7. Default features are installed automatically and are, therefore, recommended as well.

As you can see, IIS 7 is extremely modular-much more so than any previous version. Make sure you properly document each of the components you install. Also, if you find that you installed a component and are not using it, uninstall it. To do so, right-click the role in Server Manager and select Remove Role Services.
