What is a TPM, and why does Windows 11 require one?
Briefly

A TPM, or Trusted Platform Module, is a secure cryptoprocessor designed to handle security tasks and manage encryption keys, minimizing the risk of unauthorized access.
The TPM architecture, defined by an international standard for over 20 years, focuses on integrity, protection, isolation, and confidentiality to enhance computer security.
Introduced with Windows 11, the stringent requirement for TPM 2.0 aims to bolster security features such as Secure Boot, BitLocker, and Windows Hello.
Most PCs designed since 2016 are equipped with a TPM 2.0, as manufacturers were required to include this feature for systems intended to run Windows.
