Why your computer is good but still can’t run Windows 11?

In fact, Microsoft has been a bit “tricky” in this regard. On the Windows 11 introduction page, the software giant states that the minimum configuration to run Windows 11 is to have TPM (Trusted Platform Module) 2.0. This new version of TPM has just been released, so most computers released before 2017 will not have it.

However, on its internal site, Microsoft divided the minimum configuration to install Windows 11 into 2 floors, Hard Floor and Soft Floor. Devices that do not meet Hard Floor will not be able to install and update to Windows 11. Meanwhile, computers that do not meet Soft Floor will be advised not to install or update but can still install , update normally.

In the Hard Floor section, the requirement to install Windows 11 is only the TMP 1.2 feature combined with SecureBootCapable. TPM 2.0 requirements are in the Soft Floor section.

It seems that the Windows PC Health Check tool checks the user’s computer against the TPM 2.0 standard and falsely reports to the user. This makes a lot of people complain that even though they own a computer with a terrible configuration, they are still not eligible to install Windows 11. Some people even successfully install Windows 11 (dev version) but when running Windows PC Health Check still got the “Can’t run Windows 11” message.

How to turn on TPM 2.0 to fix “This PC Can’t Run Windows 11” error

What is TPM?

TPM, or Trusted Platform Module, is a hardware-based security solution. It’s a chip that is installed directly on the motherboard to protect the system against malware and other attacks. It is also an integral part of Windows security tools, such as the Bitlocker drive encryption feature.

Windows 11 recommends a TPM 2.0 chip in the system for upgrade, although TPM 1.2 will meet the minimum criteria. Microsoft requires this technology to improve customer security – although many experts consider these specifications to be overkill.

So, if you want to upgrade to Windows 11, you have to discover if your computer has TPM and what version of TPM you have access to.

What is Secure Boot?

Secure Boot is a UEFI feature that only allows signed operating systems to work, which can help protect you from malware. In addition to checking the BIOS, you can check System Information in Settings to see if your system supports Secure Boot.

Windows 11 requires TPM 2.0 and Secure Boot

For some PC systems, the root of the “This PC Can’t Run Windows 11” error problem in PC Health Check is Secure Boot and TPM in UEFI has been disabled. This is the basic system that allows the operating system to work seamlessly with your PC’s hardware. Many people are still in the habit of calling UEFI “BIOS,” even though that term technically refers to an older standard.

After enabling TPM and Secure Boot, it is possible that your PC will pass the Windows 11 “compatibility test” if it meets all other system requirements.

How to Enable TPM and Secure Boot in UEFI

To enable TPM and Secure Boot in UEFI, you need to turn off your device completely first. When you turn it back on, there will be a special key or button that you need to press at the right time to access the system’s UEFI settings screen.

The exact key you need to press depends on the device you’re using, so you’ll need to consult your device’s manual or perform a web search query regarding your device’s name along with keywords like “BIOS key” or “UEFI key”. On some motherboards (especially self-built PCs), you may see a small message on the screen at startup, telling you which key to press to enter the BIOS settings. TipsMake.com has a general article related to this issue, please refer to:

For example, on the Acer Spin 3 laptop we have here, you can access the UEFI configuration menu by powering on the device, then pressing F2 on the keyboard when you see a screen with the “Acer” logo. appear.

Once in the UEFI setup screen, instructions on exactly how to enable Secure Boot and TPM will also vary considerably from device to device/manufacturer. But in general, what we are looking for are the “Security” or “Boot” options.

In this “Setup Utility by American Megatrends” example (your setup may look different), you can find the TPM options under the “Security” tab. Look for “TPM” and make sure it’s turned on. If not, change the setting in your specific UEFI to enable it.

Similarly, in this example, the option to install Secure Boot can be found under the “Boot” tab. Navigate to the “Secure Boot” option and make sure it is enabled.

Then, make sure you’ve saved the changes you’ve made to UEFI before exiting the configuration utility (usually select “save and exit”).

(Note: If you don’t see TPM or Secure Boot options on your computer’s UEFI or BIOS settings screen, your PC may be too old to have these features, and of course can’t. running Windows 11).

After exiting UEFI, your PC will reboot and Windows will load as normal. Run PC Health Check again and hopefully everything is fixed.

How to upgrade TPM 1.2 to TPM 2.0

If you find that you have a TPM 1.2 chip, you can upgrade to TPM 2.0, it all depends on your hardware, manufacturer and firmware. That is why the article will not be able to provide exact details on how to upgrade TPM 1.2 to TPM 2.0.

If you complete an Internet search for your hardware type and the phrase “upgrade tpm 1.2 to tpm 2.0” you may find some helpful search results, guiding you through the process.

Can you enable TPM to upgrade Windows 11?

If your computer has a built-in TPM 1.2 chip or higher, just make sure it’s activated to run Windows 11. Activation varies between motherboard types and models. You must check your computer’s documentation for exact instructions.

TPM availability varies between motherboards, but most new devices already have them installed. Indeed, Microsoft has required TPM 2.0 chips for all new hardware since 2016. However, if you have an old PC and don’t have a TPM chip, the only solution you have is to upgrade your device. .
