The entire message states, “This PC can’t run Windows 11—While this PC doesn’t meet the system requirements to run Windows 11, you’ll keep getting Windows 10 updates”. Following this, a few users also received the following errors, “This PC must support TMP 2.0 and This PC must support Secure Boot”. For a detailed discussion, continue reading below:

Process of fixing the “This PC Can’t Run Windows 11” error:

The “This PC Can’t Run Windows 11” occurs despite a system meeting all the minimum requirements issued by Microsoft. Even though if your computer has enough hardware, the PC Health Check application will still show that Windows 11 is not compatible with your System. 

Now, as per reports, the problem with this error does not really connect to the hardware only, but with the presence of a TPM (Trusted Platform Model) 2.0 chip on the motherboard and the BIOS setting, Secure Boot that needs to be enabled.

Here are the details for the minimum system requirement for Windows 11

  • Processor: 1 GHz or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC)
  • Memory: 4 GB RAM
  • Storage: 64 GB or more
  • System Firmware: UEFI, Secure Boot Capable
  • TPM: Version 2.0
  • Graphics card: DirectX 12compatible Graphics/ WDDM 2.x
  • Display: >9” with HD resolution (720p)

WAY 1: Ensure your motherboard has a TPM 2.0 chip:

Now to ensure the issues does not arise in your computer, first of all, make sure that your motherboard has a TPM 2.0 chip. Some truly old machines might lack in it, though most of the new machine has this component already. To find this for your System, follow the steps given below:

  • Firstly, launch the RUN dialogue box by pressing Windows + R altogether.
  • Now inside the empty text box, type tpm.msc, click on OK, and it will launch the Trusted Platform Module (TPM) Management console.Trusted Platform Module (TPM) Management on Local Computer
  • On the Trusted Platform Module screen, check the value of the Specification Version (The Value should be 2.0).

However, in case you are unable to see the console screen or receiving an error message, the Compatible TPM is not found, then it means either the TPM chip is disabled in your BIOS or it is not available on your motherboard.

Consider enabling the TPM chip directly from the BIOS.

Way 2: Download and change the appraiserres.dll file:

As per some suffered users they finally managed to solve the “This PC can’t Run Windows 11”  issue  by Replacing the appraiserres.dll file. To know how it is, follow the below given steps,

  • To begin with, either download the appraiserres.dll file from Windows 10 ISO or from an external source.
  • Now mount the Windows 11 ISO and then navigate to the Source folder.
  • Here inside the folder, locate the appraiserres.dll file and then delete it.
  • Further copy the appraiserres.dll file, which you downloaded in the first step and then paste it into the Windows 11 ISO.
  • Now retry installing Windows 11 on your computer, and you might not receive the said error again.

Way 3: Check if Secure Boot is enabled:

Not all machines have the Secure Boot feature enabled, and Microsoft claims that Windows 11 requires a machine that is Secure Boot capable. Here the simplest feature is to switch ON the Secure Boot. For doing so, follow the steps given below:

  • Firstly, restart your computer and then enter the Boot menu.
  • Depending upon the System you are using, press F2, F11 or the Delete key before booting into Windows.
  • Now from the Boot menu, locate the option Secure Boot and ensure that it is enabled.

Note: The process will differ from one BIOS version to another.

  • Lastly, you can check PC Health Check Utility, and you will receive the following message stating, “This PC can run Windows 11”. The same message now will be changed on the Microsoft official requirement page.
NOTE: Some users might end up with a mess where their System might not boot up because no operating systems have been detected. If this happens with you, then you will require to use a disk converter for switching your disk from the Master Boot Record (MBR) to the GUID Partition Table (GPT) partition style (without modifying or deleting data on the disk).

Make sure you create a backup of your data before doing that. Also, after you convert your disk to GUID Partition Table, disable the Legacy or CSM boot from BIOS before booting.
