Using Bitlocker and TPM 2.0 on Windows 7
TPM is a method of storing the encryption key used by Bitlocker to protect the contents of the Windows drive. Typically the new Skylake platform systems and newer have moved from TPM 1.2 to TPM 2.0. This is natively supported by Windows 10.
If you want to use TPM 2.0 on Windows 7 then this is possible, but only with the following:
Stonebook Pro and Stonebook Lite
The Skylake Stonebook Pro and Stonebook Lite notebooks support Windows 7 and UEFI mode. This support was added in the 6/9/16 BIOS update. Without this BIOS, the system will not be able to operate in UEFI mode with Windows 7, meaning that TPM functionality will not be available. If you switch from non-UEFI (legacy) to UEFI modes, you may need to remove the partitioning information on the notebooks hard drive to complete your operating system deployment.
