How to install Windows 11 without TPM 2.0

Windows 11 has not only brought a fresh design and new features. It also comes with higher minimum requirements, especially when compared to its predecessor, Windows 10. One of the most controversial ones is the need for a TPM 2.0 chip, something that older devices do not have. Although the restriction comes from Microsoft, the company itself has provided a safeguard to install its new operating system despite not having this component. This is a complete guide that shows you all the necessary steps to install Windows 11 without TPM 2.0.

What is TPM 2.0 and what is it used for?

TPM stands for Trusted Platform Module. It is a hardware device that includes several security features to enhance the security of the equipment. It handles tasks related to data encryption of important data, such as the user's biometric information to unlock the operating system. You should know that TPM 2.0 is a chip that comes included in all devices launched as of 2016.

Before this, there was another version, TPM 1.2, included in most of the equipment before that date. Unfortunately, Windows 11 can only be officially installed on computers running the current version, 2.0. However, to everyone's surprise, Microsoft has explained a way to bypass this limitation. Keep reading to learn more about it.

Windows 11 full minimum requirements

Before we get down to work, you should know that you will only be able to install Windows 11 without TPM 2.0 if you meet the rest of the minimum requirements set by Microsoft. They are the following:

  • Processor. Clock frequency of 1 GHz or higher. CPUs with two or more with 64-bit architecture.
  • RAM. 4GB or more.
  • Storage. At least 64 GB is required. It may require additional space for downloading updates and enabling specific features.
  • Graphic card. Must support DirectX 12 or later and have a WDDM 2.0 driver.
  • System firmware. UEFI with secure boot.
  • Screen. 720p resolution or higher. Monitor 9 inches or larger with 8 bits per color channel.
  • Internet connection. Required for Windows 11 Home edition

Additionally, your equipment must have at least TPM 1.2. Therefore, this method is not compatible with equipment that does not have any kind of TPM chip.
