Turn On/Off Bit Locker- Windows 7

Bit Locker
Bit locker drive encryption allows a user to help protect data from hackers, loss or theft.

Available in Windows 7 and available in the Ultimate and Enterprise editions, Bit Locker helps keep everything from documents to passwords safer by encrypting the entire drive that Windows and your data reside on. Once Bit Locker is turned on, any file you save on that drive is encrypted automatically.

Bit Locker To Go—a new feature of Windows 7—gives the lockdown treatment to easily-misplaced portable storage devices like USB flash drives and external hard drives.

System requirements for Bit locker Drive Encryption:

• Computer that meets the minimum requirements for Windows 7 or Windows Server 2008 R2. 

• A TPM microchip, version 1.2, turned on for use with BitLocker on operating system drives is recommended for validation of early boot components and storage of the BitLocker master key. If the computer does not have a TPM, a USB flash drive may be used to store the BitLocker key.

• A Trusted Computing Group (TCG)-compliant BIOS for use with BitLocker 

on operating system drives.

• A BIOS setting to start up first from the hard drive, not the USB or CD drives.

How to turn ON Bitlocker

1. Open Bitlocker Drive Encryption by clicking the Start button, clicking Control Panel, clicking Security, and then clicking Bitlocker Drive Encryption. 

2. Click Turn On BitLocker. This opens the BitLocker setup wizard.  If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

3. Follow the instructions in the wizard.

How to turn off BitLocker Drive Encryption

1. Click Start, click Control Panel, click System and Security, and then click BitLocker Drive Encryption.

2. Find the drive on which you want BitLocker Drive Encryption turned off, and click Turn Off BitLocker.

3. A message is displayed, informing you that the drive will be decrypted and that decryption may take some time. Click Decrypt the drive to continue and turn off BitLocker on the drive.

    Can bitlocker be locked down to files and folders? I thought the whole point of bitlocker was that someone couldn't steal your PC and image it or remove the HD as THE WHOLE DISK was encrypted. If you can log into the PC then bitlocker is over. You now can access anything? Right?

    The requirements of system for running Bit Locke are slightly different and it depends on whether you will be encrypting an operating system drive or a data drive.
