Understanding BitLocker
Microsoft Help:-
BitLocker has been improved for Windows 7 to include
BitLocker To Go. Protecting your data from loss or theft is Important in today's
world. You can encrypt your entire hard drive. Once it's activated, all the files
that you create, use, and save are automatically encrypted. The BitLocker To Go
feature now includes all your portable storage devices.. Go—Vista introduced BitLocker, an encrypted and secure form of on-disk storage
that only those with the right password can access. In Windows 7, BitLocker to Go extends this
capability to USB drives, including USB flash drives (UFDs), so that you can secure some or all of
the contents on drives or devices that you take with you on the road. This is a great way to protect
against unwanted disclosure resulting from theft or loss of a notebook or a portable storage
devices of some kind. The Ultimate Edition combines every thing from all the editions into one complete
package. Windows 7 Ultimate provides the power and security features needed
for work, such as BitLocker and the use of different languages
If you have a two NTFS drive partitions (also known as volumes)—one
for the system boot volume and one for the operating system volume—
and a computer with a compatible Trusted Platform Module (TPM)
microchip and BIOS, you can use BitLocker to encrypt the operating
system volume. If you have other internal volumes with data, you can
also use BitLocker to encrypt it. BitLocker helps protect your system
and blocks hackers from accessing sensitive information behind the
scenes. With BitLocker To Go (New!), you can apply the same protection
to portable storage devices, such as USB flash drives and external
hard drives. When you add files to your computer, BitLocker automatically
encrypts them. When you copy files to another location, the files
are decrypted. After you turn on BitLocker, it’s critical that you create a
recovery password, because BitLocker locks up the entire drive if it
detects a problem during startup. The encrypted data volume automatically
unlocks when the system boots into the operating system volume.
Use BitLocker to Encrypt Files
- Click the Start button, and then
click Control Panel.
- Click the BitLocker Drive
Encryption icon in Small icons or
Large icons view.
- Click Turn On BitLocker on the
volume you want.
- Follow the wizard to save a recovery
password, save or print the
recovery key, click Start
Encrypting, wait for BitLocker to
encrypt the volume upon restart,
and then click Close.
When your computer starts up
after the encryption, you won’t see
any change. If a problem occurs or
someone tries to illegally access
your operating system, your
computer switches into recovery
mode until you supply the recovery
password.
- To turn off BitLocker, click Turn Off
BitLocker, and then click Decrypt
Drive. To change or remove a
password, save or print a recovery
key, or automatically unlock a
drive, click Manage BitLocker.
