How to Fix "This PC can't Run Windows 11" Error

 I'm sure that the launch of Windows 11 is no longer news to most of us and I'm also sure most of us have run Microsoft's PC Health check to confirm if their current PC is eligible to install Windows 11 OS.

Well, if you got the "This PC Can't Run Windows 11" error, then there's a possibility you need to either enable TPM and Secure Boot on your PC.

Discussed below is how to do so.

Main Causes of Can't Run Windows 11 Error

Most PCs have a common problem which is disabled TPM and Secure Boot in UEFI, which is the basic system that allows your Operating system to work with your PC hardware.

In summary, Secure Boot is a feature that allows only signed OS to work thereby protecting you from malware Meanwhile TPM(Trusted Platform Module) helps in data encryption through the help of a special chip. Most machines built after 2016 carrying TPM 2.0 chips can run Windows 11.

After enabling these two features (TPM and Secure Boot), I'm quite sure your PC will pass the windows 11 compatibility test, provided it is not deficient in other system requirements.

Although many people still refer to their "UEFI" as "BIOS", it still the same thing just that the latter term refers technically refers to the older standard.

How to Enable TPM and Secure Boot in UEFI

These two features can be enabled in your PC UEFI settings, all you need to do is turn off your PC and turn it on but this time you would interrupt the boot process by pressing a special key or button at the right time to be directed into the UEFI settings.

Although the exact key differs depending on manufacturers, so you need to perform a web search or browse through your PC manual on guide on how to get to your BIOS settings.

In addition, some motherboards provide a short message at boot telling you which key you need to press to enter into your BIOS settings.

For Example, you can access some PC UEFI configuration menus by hitting F2 on start-up, meanwhile, these settings can be accessed by F12 on other laptops.

Now, once you're in your UEFI setup screen, you will find the TPM and Secure Boot under the security and "boot option.

1. Firstly, Navigate to the "Security" tab and look for "TPM" and make sure it is enabled. Enable it if it's not enabled.

2. Similarly, you can find the "Secure Boot" option under the "Boot" tab. checkout for it and make sure it is enabled.

3. Finally, do well to save changes made to these programs in your UEFI before you exit the configuration utility.

NOTE: If you don't see anything related to TPM or Secure Boot on your PC's UEFI or BIOS setup screen, then your PC may be too old to have these features.

To Check your TPM Chip, you can Press Windows +R and input tpm.msc, then press enter, you should see your TPM information under the specification version on your PC's TPM Module.

That's it.

After hitting the exit button, your PC will restart and you can proceed to run the compatibility check again, your PC will hopefully pass the test.

If these features are enabled and your PC doesn't pass the check, there's another reason your machine isn't compatible with Windows 11.
