On this Help protect your computer and improve Windows automatically screen, Windows 7 is asking you do choose how you want to automatically install updates from Microsoft's Windows Update service.
I recommend that you choose Install important updates only. This option is the safest because it restricts Windows 7 from doing anything with your data or to your computer automatically except when important security and stability updates are available.
You are more than welcome to choose Use recommended settings but I do not recommend that you choose Ask me later.
Note: These settings can easily be changed within Windows 7 after you're done stepping through these configuration questions.
