BitLocker then turns on your computer’s Trusted Platform Module (TPM) chip, which is a microchip that enables your computer to utilize advanced security features.Start BitLockerInitially, when you start BitLocker, you can create a personal identification number (PIN) that you can use each time you start your computer, or you can designate a startup key that you must enter each time that you attempt to access a USB drive. This additional protection is optional, but is recommended. If you are going to use DirectAccess as your remote-connectivity software solution, you must create a PIN.To start BitLocker and create a PIN or startup key:Click Start , click Control Panel, click System and Security, and then click BitLocker Drive Encryption.Ensure your computer’s TPM is turned on. To do this, look for a TPM Administration link in the lower-left corner of the window under See also.If you do not see this link, the TPM is not on. For assistance in turning it on, contact << helpdesk contact or technical support URL>>. Click Turn On BitLocker.On the Set BitLocker startup preferences page, click Require a PIN at every startup.Important<<Organization >> recommends using a PIN or startup key because it is the most secure option. You must create a PIN if you are going to use DirectAccess as your remote-connectivity software solution.On the Enter a numeric startup PIN page, in the PIN field, type a number that is between 5 and 20 digits in length. The longer your PIN number, the more secure your computer will be. In the Confirm PIN field, retype the number.Click Set PIN.On the How do you want to store your recovery key? page, click one of the following options:Save the recovery key to a file. Microsoft IT recommends this option, which enables you to save your password to a network file-share folder, such as My Site.Print the recovery key.Click Next.On the Encrypt the drive page, select the Run BitLocker System check box, and then click Continue.
