What is a TPM chip and why does Windows 11 need one?

A TPM chip is a tiny security device inside your computer that keeps sensitive information like passwords and encryption keys locked away safely. Windows 11 needs it to protect your files and keep your computer more secure. If you're upgrading to Windows 11, your computer needs a TPM 2.0 chip. That's a specific version that's been standard on new computers since 2016.

A TPM chip is like a vault built into your computer's motherboard. It holds onto sensitive information like passwords and encryption keys and keeps them safe from hackers. Windows 11 uses it to encrypt your hard drive and protect your files so even if someone steals your computer, they can't read what's on it. Microsoft made TPM 2.0 a requirement for Windows 11 because the extra security is important in a world where hacking and data theft are common.
