How to fix Windows 11 that says “Your processor is not supported”

So you’ve heard all about the Windows 11 operating system. You know many people who have taken advantage of the free upgrade to Windows 11 and either love it or hate it. Now you are looking forward to finally trying it out.

Unfortunately, you have discovered that when you try to upgrade to Windows 11, there is an error that says that your computer’s processor is not supported. What can you do?

Although the error causes many people to run to the store to buy a new computer, you can work around the error and still install Windows 11.

Should you install Microsoft Windows 11 with an unsupported CPU?

Every computer is different and the reasons for Windows 11 incompatibility may vary from system to system. You can even upgrade a Windows 7 PC if it meets all the hardware compatibility requirements.

The most common reason why your system does not meet the “minimum system requirements to run Windows 11” is an incompatible CPU. To check Microsoft’s list of supported Intel processors and list of AMD processors to see if yours is included.

You can confirm this by opening your Windows settings and selecting: Windows Update from the left menu.

You will likely see the red X icon next to the message, “This PC does not currently meet the minimum system requirements to run Windows 11.”

Running the PC Health Check Tool

Below is a link to access the PC Health Check app. This tool will scan your computer and give you the specific reasons why your computer is not compatible with Windows 11.

When you first start the tool, select the Check now button to start the scan.

When it is done, you will again see the message that your system does not meet the minimum hardware requirements. But this time it mentions the main reason why your system is incompatible.

The main reason for your system is probably “The processor is not currently supported for Windows 11.”

If you select: View all resultsyou will see other reasons why your system may not be compatible with Windows 11. This could be TPM 2.0, available RAM, Secure Boot or your CPU.

You can enable Secure Boot Settings in your BIOS by changing the PC Boot Mode from “Legacy” BIOS to UEFI/BIOS. Note that this is only the case if your BIOS has this feature available.

You will also see where your system IS compatible. Hopefully the only reason your system isn’t compatible is the processor and nothing else. Ideally, your system should have at least TPM 2.0 enabled. But even if it doesn’t, you should still be able to install Windows 11 if you want to.

Remark: Most importantly, you need a minimum of 4 GB RAM, otherwise you will not be able to install Windows 11 using the workaround described in this article.

Need to install Windows 11 on an incompatible computer?

If your system is incompatible with Windows 11 only because of the CPU and no other unsupported hardware, then you have the least risk of having problems upgrading to Windows 11 anyway. However, the risks are not zero.

According to Microsoft, anyone who installs Windows 11 on an unsupported PC will not receive critical Windows 11 updates.

Next to this, Microsoft claims that

“Installing Windows 11 on this PC is not recommended and may lead to compatibility issues. If you continue to install Windows 11, your PC will no longer be supported and you will not be entitled to updates. Damage to your PC due to lack of compatibility is not covered by the manufacturer’s warranty.”

This “damage” can mean a higher chance of more Blue Screen of Death (BSOD) errors or of your computer freezing or crashing.

What about TPM 2.0?

If you noticed in the list of incompatibilities that one of those issues is the lack of Trusted Platform Module (TPM) 2.0, you can still install Windows 11. However, you accept some additional security risks.

TPM is a physical chip in most modern computers that prevents malicious software (malware) from running. If TPM 2.0 is not enabled on your computer, this may not mean that your computer does not have this feature. You just need to enable it in the BIOS or purchase a TPM module.

Do I still need to upgrade to Windows 11?

This means that nothing will stop you from upgrading to Windows 11 using this guide. However, you accept a certain risk if you switch to this new operating system. Your system may not receive new Windows updates and you may start seeing more BSoD errors.

Many computers that stay on Windows 10 may encounter problems receiving newer security updates anyway. For example, this author experienced an endless update cycle where Windows 10 updates failed and had to be removed every time the computer was restarted.

In such a case, you really have nothing to lose by upgrading to this new version of Windows on an incompatible device and enjoying all the new features. It will at least help you avoid having to buy a new PC for another year or two.
