The Trusted Platform Module (TPM) is an on-board hardware component designed to enhance security by providing a protected space for key operations and other security-critical tasks. Using both hardware and software, the TPM protects encryption and signature keys at their most vulnerable stages.
To use the TPM feature set that is provided in Windows Server 2008 R2, you must configure your server to support this feature. For instructions, refer to the TPM information in the documentation of your server.
For additional information about implementing this feature, refer to the Windows Trusted Platform Module Management documentation provided by Microsoft.
