Windows Filtering Platform
The Windows Filtering Platform (WFP) architecture in Windows 7 helps software companies create
rewalls, antivirus software, and other types of applications and services that work with Windows. For
example, third-party developers can use the WFP to create a product that selectively turns parts of the
Windows Firewall on or off, which allows you to choose which software rewall you want to use and have
it coexist with Windows Firewall. As a result, you’ll have a wide range of choices for security software, yet
know that they will work with your PC running Windows 7.
BitLocker
Each year, hundreds of thousands of PCs
are retired, lost, or stolen. BitLocker, which
was rst introduced in Windows Vista, gives
you a way to encrypt your hard disk drive
to better protect data in case your laptop is
stolen or lost. In Windows 7, we’ve improved
BitLocker in many ways. For instance, you can
now right-click a drive to enable BitLocker
protection. In addition, you no longer need
to repartition your hard disk drive, because
BitLocker automatically creates the neces-
sary hidden boot partition. It’s also easier to
recover your data with Data Recovery Agent
(DRA) support for all protected volumes.

BitLocker To Go
There are numerous ways you can lose your data without losing your PC, especially if you use USB
ash drives and other personal storage devices. For example, you might want to take your household
budget to a meeting with your nancial advisor or transport some
work to a PC in your home using a removable storage device.
BitLocker To Go extends support for BitLocker drive encryption
to USB removable storage devices, such as ash memory drives
and portable hard disk drives, helping protect the data on those
devices if they’re lost or stolen. When you use BitLocker to Go,
your data will be protected with a password, helping to ensure
that only authorized people can access it. In addition, you can
view the information on a device using BitLocker To Go with a PC
running Windows XP or Windows Vista.
