Microsoft finally revealed the long-rumored Windows 11 at their event. It looks great in terms of visual changes as well as its feature set. The new Windows 11 includes a new Start menu and a centered taskbar. It also supports Android apps on Windows 11.

Microsoft has also released a PC Health Check App that allows you to check if your PC can run Windows 11. Many users report that Windows 10 PCs running Windows 11 are still getting this error. We investigated the issue and found a solution and possible explanation for this error. Let’s get started.

All You Need to Know about “This PC Can’t Run Windows 11” Error (2021)

We have discussed the problem and provided a solution. If the solution doesn’t work, you can move on to the final section to explain why the issue is occurring.

Why does PC Health Check App throw the “This PC can’t run Windows 11” error even on modern PCs?

Microsoft is working to improve security in Windows 11. The work of creating a secure Windows started in 2017. Microsoft required OEMs to include a TPM module (a type of security chip) in their desktops and laptops. The TPM module protects passwords, manages Bitlocker, authenticates credentials, and many other things.

Since 2017, all Windows machines have a TPM module. It can be either TPM 1.2 or TPM 2.0. The problem is, most PCs have left the TPM module disabled by default. That is why the PC Health Check app keeps showing a “This PC Can’t run Windows 11” error. By pressing Win + R shortcut, you can check the availability of TPM by running tpm.msc.

There seems to be confusion about the TPM version. Microsoft states that Windows 11 requires TPM 2.0 as the minimum system requirement. The official Compatibility Doc for Windows 11 states that there are two Floors: Hard Floor and Soft Floor. Windows 11 will work under the Hard Floor even if you have 1.2 TPM.

Some motherboards don’t come with a TPM Module for custom-built computers. Amazon sells compatible TPM chips that are compatible with your motherboard. Many motherboard manufacturers make a TPM chip that can plug into the TPM slot.

In a few easy steps, fix the “This computer cannot run Windows 11” error.

  1. You first need to reboot into your computer’s BIOS (or UEFI) interface. You can do this by pressing the boot key continuously as your computer starts.

Notice: It’s usually the Esc or F10 key for HP laptops. The boot key for other laptops or desktops may be different. You can find the exact boot key for your computer on the internet. The manufacturer of the motherboard determines the boot key for a custom-built desktop.

  1. Look for “TPM,” or Trusted Platform Technology, once you’re in the BIOS/UEFI interface. On some Intel-based machines, it’s also known as PTT (Platform Trust Technology). You might see TPM mentioned in the BIOS menu on AMD machines. Please take a look around and check the Advanced Settings to make sure it is enabled. You might also see TPM State, so make sure you enable it.

3. Next, locate the “Secure Boot” option under various menus and activate it. You will need to create a BIOS password if the Secure Boot option is grayed out. You can’t enable Secure Boot on some laptops unless you have a Supervisor or Administrator password. You can then enable Secure Boot by setting the password first. It would be best if you remember your password. Otherwise, it will lock your computer, and you won’t have access to the BIOS.

4. Some users reported that activating Virtualization in the BIOS/UEFI is enough to install Windows 11. You can also enable Virtualization Technology in the BIOS/ UEFI. can describe virtualization as:

5. To save or exit, press F10 and hit enter. F10 is reserved for Save and Exit; however, your computer’s key might be different. It is recommended that you verify it in the BIOS/UEFI footnote.

6. Your computer will now reboot to Windows 10. Click on “Check Now” in the PC Health Check app. The “This PC Can’t Run Windows 11!” error should now be gone. Now, you should see the message “This computer can run Windows 11”.

7. For a possible explanation, if you still get the “This PC Can’t Run Windows 11” error, try the next section.

Are Your Windows 10 PCs Still Not Compatible with Windows 11 Despite Enabling TPM?

If you have all of the required hardware to run Windows 11 but still receive the same error message, it is most likely that the problem is with your CPU. Microsoft has published a list of compatible processors for Windows 11, both Intel and AMD. It appears that major Intel Core processors like i3, i5, and i7 are supported. However, you will need to have an 8th-Gen or higher CPU to install Windows 11. That is quite a surprise. The Windows 11 compatibility test will not pass if your Intel processor is below 8th-gen.

Windows 11 supports AMD processors, including Athlon and EPYC, as well as the Ryzen processor series. Windows 11 is compatible with Ryzen processors built on Zen+ architecture and above. All AMD processors released after 2018 are compatible with Windows 11.

The bottom line is that if your machine meets the other requirements, you are eligible for the Windows 11 update. Find out when the Windows 11 update will be available, whether it is the Insider preview build, stable release, or both, in this linked article.

If the app gives an error after you have passed the CPU test, it is most likely a bug. Steve Dispensa (VP of Product Management at Microsoft) confirmed that they would soon update the PC Health Check app. You might wait to get the update and make sure your computer is compatible with Windows 11.

All that said, if your computer is not supported by Windows 11, meaning it is on an older CPU or doesn’t have a TPM chip, you don’t need to be concerned.

Microsoft will provide Windows 11 updates for Windows Insiders that don’t comply with the requirements. There is a way to install Windows 11 on non-supported devices. We will have to wait to see if Microsoft decides to relax the restrictions or if the developer community finds ways for Windows 11 to install unsupported devices (barring 32-bit computers). According to my knowledge, older CPUs can run Windows 11.

How to fix the “This PC can’t run Windows 11” error

Was our comprehensive guide and explanation on why the PC Health Check keeps throwing an incompatibility error? As I mentioned, the problem is most likely caused by an unsupported CPU. That’s all we have to say. The linked articles will provide information about the Windows 11 system requirements and the features that Microsoft has removed.
