TPM Support enables or disables TPM (Trusted Platform Module) support. The
TPM is a component on your computer’s mainboard that is specifically
designed to enhance platform security by providing a protected space
for key operations and other security critical tasks. Using both hardware
and software, TPM protects encryption and signature keys at their most
vulnerable stages – operations when the keys are being used
unencrypted in plain-text form. TPM is specifically designed to shield
unencrypted keys and platform authentication information from
software-based attacks.
NOTE:
 To use the TPM feature, the TPM driver supplied with your computer must be
installed.
 The next two items Current TPM State and Change TPM State would only appear
if the item TPM Support is set at Enabled.
Current TPM State shows the current TPM state.
Change TPM State allows you to select between No Change, Clear,
Deactivate & Disable, and Enable & Activate.
