As of 11/17/21, Microsoft states that a Trusted Platform Module (TPM) version 2.0 is required to upgrade to Windows 11. Most motherboards do not feature this component, instead offering a header for you to install the module separately.

Motherboards without a discrete TPM 2.0 module may still meet the requirements for Windows 11 through manufacturer specific security solutions such as AMD Ryzen’s firmware TPM (fTPM) and Intel’s Platform Trust Technology (PTT).
You can generally enable these options in the motherboard’s BIOS if you have a CPU listed below.
Compatible AMD Ryzen CPUs:
- Ryzen 2000 series
- Ryzen 3000 series
- Ryzen 5000 series
Compatible Intel CPUs:
- Intel 8th Gen (Coffee Lake)
- Intel 9th Gen (Coffee Lake Refresh)
- Intel 10th Gen (Comet Lake)
- Intel 10th Gen (Ice Lake)
- Intel 11th Gen (Rocket Lake)
- Intel 11th Gen (Tiger Lake)
In addition to those hardware requirements, you will also need to convert your operating system’s drive file system from MBR to GPT.
Once you have confirmed that the file system is GPT, you will need to change or disable CSM (Unified Extensible Firmware Interface) or Legacy Boot Mode and enable UEFI/BIOS (Unified Extensible Firmware Interface) in order to enable “Secure Boot.”
