BitLocker Drive Encryption provides protection for operating system and data 
drives by encrypting the contents and requiring users to authenticate their 
credentials to access the information. On the operating system drive, BitLocker 
uses the compatible Trusted Platform Module (TPM) to detect if the computer's 
startup process has been modified from its original state.

Disabling BitLocker Drive Encryption is a temporary method for removing 
BitLocker protection without decrypting the drive Windows is installed on. 
Disable BitLocker before modifying the server’s hardware configuration or 
startup files. Enable BitLocker again after the maintenance procedure is 
complete.

V

– With BitLocker features enabled, modifying the system configuration 

(hardware or firmware settings) may render the system inaccessible. 
The system may enter Recovery Mode and require a 48-digits 
recovery password to return to normal operation.

Ensure to disable BitLocker drive encryption before maintaining the 
server.

– When disabled, BitLocker uses a plain text key instead of the Trusted 

Platform Module (TPM) to read encrypted files. Keep in mind that 
information on this drive is not secure until BitLocker has been re-
enabled.

Ê

Ask the system administrator to disable BitLocker-protection on the 
operating system drive, using the BitLocker setup wizard available either 
from the Control Panel or Windows Explorer:
