• Restarting the computer for maintenance without a PIN or startup key
• Updating firmware when a TPM is installed
• Upgrading critical early boot components
• Replacing the system board
• Replacing the system board to replace or remove the TPM
• Disabling or clearing the TPM
• Moving a BitLocker-protected drive to another server
• Adding an optional PCI device, such as a storage controller or network adapter
