TPM concerns due to mode selection:

Windows 7 using TPM 2.0:

Dell now supports TPM 2.0 on Windows 7 64bit with  UEFI enabled and Secure Boot disabled in Platform BIOS Setup.

Windows 10 using TPM 1.2:

Dell recommends using Windows 10 with the TPM in 2.0 mode.  Newer Windows 10 security features may not be available when the TPM is in 1.2 mode.  For the latest information on available TPM 1.2 and 2.0 features in Windows 10, please consult Microsoft documentation.
