What is the ACPI\MSFT0101 Device?

The Device

The device is a chipset component found on Intel Skylake and newer motherboards. It is part of Intel Platform Trust Technology (PTT) as can be used to provide TPM 2.0 functionality. The device can therefore be used to provide credential storage and key management, useful if you are deploying technologies such as Bitlocker.

Drivers and Software

This device is not installed by using the Intel Chipset Driver software or Intel Management Interface (MEI). The device is automatically supported in Windows 8 and Windows 10. The BIOS must be running in UEFI mode.

If you are using Windows 7 x64, or Windows Server 2008 R2, a Hotfix is available to add support for TPM 2.0 functionality. This will provide the driver support required. Again, the system must be running in UEFI mode.

Reminder: The ACPI\MSFT0101 device – Intel Platform Trust Technology – is not supported under Windows 7 x86.
