As you can see from the screenshots below, the process of installing Windows 7 using the interactive Setup application is very similar to that of Windows Vista. There are some differences, however. Windows 7 Setup is even more streamlined than that of Vista, and there are some interesting additions, including a Join a Wireless Network wizard (that occurs only when Setup detects wireless networking hardware) and the Setup Homegroup screen. Note, too, that the PC performance step occurs much more quickly than it does in Vista.
