ASUS recently published updated BIOS for a number of their chipsets, as well as enable the TPM, also known as the Trusted Platform Module, that Microsoft requires for the upcoming Windows 11 operating system. The BIOS updates cover chipsets from as far back as 2017 and include Intel Kaby Lake processor units.

Users have found it difficult to locate how to enable TPM 2.0 on their computers. To remind readers and users, TPM prevents attacks from affecting the boot process and your hardware by performing cryptographic operations on your hardware to secure encryption. When looking for the TPM, depending on the processor being used, the names for the setting to activate TPM 2.0 were either "PTT" or "PSP fTPM." Microsoft has started to sway manufacturers to enable TPM 2.0 automatically by default during the manufacturing process.
