BitLocker To Go Encrypts Portable Flash Drives in Windows 7

The BitLocker feature was introduced in Windows Vista and allowed you
to encrypt the content of your hard drive.  Now in Windows 7 they
offer BitLocker
To Go which allows you to encrypt portable USB flash drives.

First open up My Computer and Right-click on the flash drive you want
to encrypt and select Turn on BitLocker.
After BitLocker initialized the flash drive you will need to enter in
a password to unlock the drive.  You can also set up a Smartcard which
are usually
used in a work environment so talk to you IT staff.
Next you will be prompted to store the recovery key which is used in
the event you lose your password or smartcard.  If you store it as a
file make sure
that it is not on the same drive that you’re encrypting.
After the key has been saved as a file or printed you will see a
confirmation message.

Finally you will be ready to start encrypting the drive so just click
the Start Encrypting button.

While it is encrypting there will be a progress screen displayed.

Right-click on that icon to bring up options to manage BitLocker encryption.

The next time you plug in the drive to a Windows 7 machine you will be
prompted to enter the password to gain access to the drive.  You can
also always
have it unlocked on specific machines in the future.

You can also use the encrypted drive in Vista and XP.  Here we will
look at how it looks in XP, when you plug it in you will be prompted
for the password
to launch BitLocker To Go Reader (the utility is installed
automatically on the drive by Windows 7).

BitLocker To Go Reader is a Windows Explorer type navigation utility
for showing the content of the drive.

With a BitLocker encrypted drive you will only be able to read and
copy files.  If you need to add files or change them you will need to
use a Windows 7
machine.

This is a great way to easily make sure sensitive data on your USB
flash drive is safe.  Right now anyone who has Windows 7 RC1 Ultimate
can use this feature.
