BitLocker™ Drive Encryption
BitLocker Drive Encryption (BitLocker) is available on computers running Windows 7 Enterprise Edition and Windows 7 Ultimate Edition. Should your computer be lost or stolen, BitLocker protects your data by helping to prevent offline software attacks. Turning on BitLocker encrypts the hard drive where Windows is installed, including all information that is stored on that drive.

Device Information Retrieval
What this feature does
Device Information Retrieval downloads information from Microsoft for your hardware devices and displays it in the Windows 7 Devices and Printers control panel, and when you first install and use a device, in the Device Stage.
Choice and control
If you choose the recommended settings during Windows 7 setup, you turn on Device Information Retrieval. You can turn this feature off by going to Devices and Printers in Control Panel. Right-click your computer icon, and then click Device Installation Settings. Select “No, let me choose what to do” and click to clear the “Display enhanced device icons…” check box.

Driver Protection helps prevent the operating system from starting drivers that are known to cause stability problems. These drivers are listed in a Driver Protection List database that is stored on your computer. The Driver Protection List is updated through Windows Update and Dynamic Update (below). Driver Protection checks this database while the operating system is running. These checks are performed to determine whether to start a driver. For more information, see the Driver Protection List article online at the Microsoft website.
Dynamic Update enables Windows 7 to perform a one-time check with the Windows Update website to get the latest updates for your computer while Windows is being installed. If updates are found, Dynamic Update automatically downloads and installs them so your computer is up to date the first time that you log on or use it.
