You are not alone; many people have reported that their machine can’t run Windows 11 despite meeting the system requirements. This error is typically caused by one of two things: either UEFI Secure Boot is disabled, or the Trusted Platform Module (TPM) is deactivated, or the TPM version is too old (Minimum requirement for Windows 11 is TPM 2.0). You must correct both or one of the problems in order to install the newest Windows 11 preview releases on your machine. Continue reading to learn how to fix the computer won’t run Windows 11 problem.

Before we go, let’s define UEFI secure boot and the Trusted Platform Module (TPM), which are the primary causes of the problem This PC can’t run Windows 11.

What is the difference between UEFI secure boot and TPM? 

UEFI is a technology that connects a computer’s firmware to its operating system, comparable to BIOS. Secure Boot is a collection of applications that determine whether your operating system is safe to execute on a computer. It’s also advised that you install Windows using the newer UEFI mode, which has additional security features like Secure Boot than the older BIOS option.

The Trusted Platform Module, or TPM, is a one-of-a-kind hardware-based security solution that puts a cryptographic chip, also known as a cryptoprocessor, on the computer’s motherboard. The TPM chip’s duty is to encrypt data sent and received by and from the computer. On Microsoft’s support site, you may learn more about TPM.

System requirements for Windows 11

Windows 11 needs relatively modern hardware and will not install on older PCs, unlike Windows 10, which was especially intended to operate on older hardware. The following are the minimum system requirements for Windows 11 as stated by Microsoft:

  • CPU: A processor or System on a Chip (SoC) with a clock speed of at least 1GHz, two cores, and 64-bit architecture is required.
  • Memory: To operate Windows 11, your machine must have at least 4GB of RAM.
  • Storage: A 64GB hard drive is the very minimum for your PC.
  • Secure Boot is supported by the system firmware, which is UEFI.
  • Version 2.0 of the Trusted Platform Module (TPM).
  • Graphics card: For Windows 11, Microsoft recommends DirectX 12 compatible graphics cards with WDDM 2.x.
  • A minimum of a 9-inch screen with HD (720p) quality is required on your PC.
  • Internet connection: To install Windows 11 Home, you’ll need a Microsoft account and access to the internet.

This computer is unable to run Windows 11.

If you’re still getting the “This PC Can’t Run Windows 11” message after fulfilling these criteria, the problem is most likely with your PC’s Secure Boot or TPM 2.0 settings. Let’s see how we can rapidly repair the issue so you can install the Windows 11 update on your computer.

Secure boot with UEFI is enabled.

First, check whether Secure Boot is activated on your machine. To do so, go to:

  • To get msinfo32, use Windows key + R, enter it in, and then click OK.
  • Now look for the secure boot state and see how it’s doing. If it isn’t already enabled, perform the instructions below to enable UEFI secure boot.

  • Close any open applications and turn off your computer first.
  • Restart it and hit F1, F2, F10, F11, DEL to access the BIOS or UEFI menu at startup (Note: The key varies depending on the manufacturer)
  • Using the arrow keys on the keyboard, go to the boot tab in the BIOS setup utility, then highlight boot mode and see whether it’s set to legacy.
  • To change the boot mode, choose it, then hit the enter key, then select UEFI from the choices. (To choose UEFI, use the up and down arrow keys and then press enter.)
  • Now, using the arrow keys, choose the Secure Boot option and press the enter key to activate Secure Boot on your PC.

The UEFI view may vary depending on the desktop or laptop manufacturer.

If the Secure Boot option is greyed out in BIOS, you’ll need to establish a password. So first set the password, and then activate Secure Boot.

Make sure TPM 1.2/2.0 is enabled on your PC after you’ve enabled Secure Boot and UEFI in Boot Mode. As a result, don’t exit the BIOS configuration menu just yet.

TPM should be enabled on your machine.

To see whether TPM is enabled or deactivated on your machine, do the following:

  • Using the Windows key + R keyboard shortcut, type tpm.msc and hit the enter key.
  • The ‘TPM Management on Local Computer’ window would appear.
  • Under the ‘Status’ column, check whether the TPM is activated.
  • If the notification reads, “The TPM is ready for usage,” it is enabled, and no further action is required. If you don’t know how to activate it, follow the instructions below.

Note: If you receive the message “Compatible TPM cannot be detected,” your machine lacks TPM.

  • Start your machine and press Esc, F1, F2, F10, F11, DEL to go to the BIOS panel.
  • Using the arrow keys, go to the Security tab, then find TPM status and ensure it is enabled. If you don’t see the enable option, hit the enter key.

Furthermore, several customers claimed that activating Virtualization in BIOS helped them resolve the problem and that their machine now enables them to install Windows 11 without error. So, in your BIOS settings, search for “Intel Virtualization Technology” or “Virtualization Technology” or “Intel VT-x” or “AMD-V” or “SVM Mode” and activate it.

  • Finally, hit the F10 key to save your changes and restart your computer.


Pro Tip: If you’re going to install Windows 11 (or Windows 10) from scratch, be sure to do it in UEFI mode to avoid any future problems.
