Which Trusted Platform Modules (TPMs) does BitLocker support?
BitLocker supports TPM version 1.2. BitLocker does not support previous versions of TPMs. Version 1.2 TPMs provide increased standardization, security enhancement, and improved functionality over previous versions. In addition, you must use a Microsoft-provided TPM driver. To check the TPM driver provider, click Start, type devmgmt.msc in the Search programs and files box, and then press ENTER to open Device Manager. Right-click the TPM, and click Properties. Click the Driver tab, and verify that the Driver Provider field displays Microsoft.
