14.4.2.1 Preliminary steps
Ê Before removing the TPM, it is necessary to remove BitLocker-protection 
from the computer and to decrypt the volume.
Ask the system administrator to turn off BitLocker-protection using the 
BitLocker setup wizard available either from the Control Panel or Windows 
Explorer:
Ê Open Bitlocker Drive Encryption by clicking the Start button, clicking 
Control Panel, clicking Security, and then clicking Bitlocker Drive 
Encryption.
I Administrator permission required. If you are prompted for an 
administrator password or confirmation, type the password or 
provide confirmation.
Ê To turn off BitLocker and decrypt the volume, click Turn Off BitLocker, and 
then click Decrypt the volume.
I Decrypting the volume may be time-consuming. By decrypting the 
volume, all of the information stored on that computer is decrypted. 
For further information on how to disable BitLocker drive encryption, 
please refer to the Microsoft Knowledge Base.
Fujitsu service partners will find additional information (also available 
in Japanese) on the Fujitsu Extranet web pages.
