Everyone wants to enjoy Windows 11 and many users are complaining to receive the error saying This PC can’t run Windows 11 error while checking if their PC is compatible.

Sadly, this happens even for machines that truly respect the minimum system requirements asked by Microsoft.

This PC can’t run Windows 11

The error message will also appear as This PC will not run Windows 11 after scanning when you are actually browsing with your machine on Microsoft’s official system requirements page.

We’ve checked this as well on a cutting-edge Dell XPS 17 machine, with monster system requirements, and we can say that the reports are valid.

Even though the PC has powerful hardware specs to move mountains, the PC Health Check application says Windows 11 is not compatible.

The problem rarely lies with the hardware of the machine itself, but more with the presence of a TPM 2.0 chip on the motherboard and a BIOS setting that needs to be enabled, called Secure Boot.

How to check if your PC is ready for Windows 11?

  1. Download the PC Heath Check application.
  2. Run the downloaded file which will install the PC Health Check app.
  3. After it installs, click Finish to open the app.
  4. Now click on the Check now button.
  5. Hopefully, you’re going to get a message that will say that This PC meets Windows 11 requirements. You can now click on See all results or on Device specifications to see which installed apps are also compatible with the new OS.

Unfortunately, you can also see this great message from the PC Health Check app just to get the bad news that your PC is not ready when you actually try to install the OS.

That’s why we prepared a few solutions to bypass the compatibility problems and install Windows 11 as soon as possible.

How can I fix the error saying This PC will not run Windows 11?

1. Check if your PC has a TPM 2.0 chip

1.1 Start the Trusted Platform Module console

  1. Press the Windows key + R to start Run, type tpm.msc, and press Enter or click OK.
  2. In the TPM Manufacturer Information screen, check the value of the Specification Version. This should be equal to 2.0, as in our screenshot.
  3. If you are receiving an error with the Compatible TPM is not found message instead, then the TPM chip is not available on your motherboard or is actually disabled in BIOS.

So, you don’t know yet if your PC has a TPM 2.0 chip. To find out for sure, you need to check that on your BIOS and activate the TPM Support.

1.2. Enter BIOS and enable TPM Support

  1. Restart your PC and enter BIOS. Usually, you need to press an F (function) or Del keys on your keyboard before Windows boots up but it’s different for each manufacturer. Check your manual in that regard.
  2. Now, go to the Advanced options on your BIOS, find the TPM Support option, and enable it.
  3. Save and exit BIOS. You ca usually do that by pressing the F10 key but that may be different for your PC.

If you don’t find any TPM-related options, it means that your PC doesn’t have a TPM 2.0 chip. You can still avoid the TPM check so follow our steps in our guide on how to install Windows 11 without TPM.

2. Download and change the appraiserres.dll file

  1. First, get the Windows 10 and Windows 11 ISO files from the Microsoft dedicated page.
  2. Look for the appraiserres.dll file in the Windows 10 kit, right-click on it, and select Copy.
  3. Mount the Windows 11 ISO.
  4. After mounting or extracting the ISO, go to the Sources folder and delete the appraiserres.dll file inside the folder.
  5. Now paste the appraiserres.dll file you copied from the Windows 10 kit in the Windows 11 Sources folder.
  6. Try installing Windows 11 on your PC again.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

The Windows 10 OS doesn’t check if a computer has a TPM 2.0 chip, so basically, by replacing the file with the one in Windows 11, you force it to bypass this process.

3. Check if Secure Boot is enabled

  1. Restart the PC and enter BIOS by pressing an F or Del keys according to the manual of your PC before Windows boots up.
  2. Search through the BIOS menu to find the location of Secure Boot option and switch it on. You can usually find it under the Security settings but this differs for each BIOS.

Microsoft claims that Windows 11 requires a machine that is Secure Boot capable, but actually, this feature needs to be switched On. Not that straightforward, right?

At the end of the procedure, you can check again with the PC Health Check Utility, and you should now receive a confirmation message.

What can I do if I still get This PC doesn’t meet the requirements?

Unfortunately, apart from the false-positive message that we talked about at the beginning of this article, there is also a possibility to get a false-negative message.

That means your PC meets all the requirements to upgrade to Windows 11, but when you visit the Windows Update section, you see the message that you can’t upgrade.

Windows 11 update false-negative message

The complete message says that This PC doesn’t currently meet all the system requirements for Windows 11. Get the details and see if there are things you can do in the PC Health Check app.

While Microsoft is working on a solution for this problem, you can still upgrade to Windows 11 by using the ISO file or the Windows 11 Installation Assistant.

You can get, however, into a mess where your system won’t boot up because no operating systems have been detected.

In that case, you will need to use a disk converter to switch your disk from the Master Boot Record (MBR) to the GUID Partition Table (GPT) partition style without modifying or deleting data on the disk.

Although it says you won’t lose any data, we would strongly suggest creating a backup of your data before doing that. However, after you convert your disk to GPT, disable the Legacy or CSM boot from BIOS before booting.

We hope that our guide helped you fix all the compatibility issues and you can finally enjoy Windows 11.
