Windows 11 requires a TPM 2.0 security processor to install or upgrade to Windows 11. Unfortunately, mistakes in support documents have causes conflicting information on what type of TPM you need and why you need it in the first place.
Many people ran the tool, they discovered it was reporting that “This PC can’t run Windows 11,” even on devices that run Windows 10 flawlessly as they do not have a TPM 2.0 installed.

Why you need a TPM
A TPM is a dedicated processor used to perform hardware-based cryptographic operations to secure encryption keys and defend against malicious tampering of your hardware and the boot process.
TPM processors come in two versions – an older and less secure 1.2 version and a more secure 2.0 version, which is a requirement for Windows 11.
Since 2013, Intel and AMD added firmware TPM technology to many of their CPUs that perform the same functionality as a TPM 2.0 processor without the need of a dedicated module.
For Intel Process, this technology is called Intel Platform Trust Technology (Intel PTT), and for AMD, it is called AMD Platform Security Processor.
“Almost every CPU in the last 5-7 years has a TPM. For Intel its called the “Intel PTT” which you set to enabled. For AMD it would be “AMD PSP fTPM”. TPMs have been required for OEM certification since at least 2015 and was announced in 2013,” said David Weston, Director of Enterprise and OS Security at Microsoft.
