Read on to learn how to install Windows 11 on unsupported hardware.

  • System firmware: UEFI, Secure Boot capable
  • TPM: Trusted Platform Module (TPM) version 2.0

We also have an article detailing the Windows 11 technical specifications that might offer a lot more information about this.

However, if you are interested in learning how to install Windows 11 on an unsupported PC, we will show you how. We’ve broken down the entire process from start to finish into simple steps.

How can I install Windows 11 on an unsupported CPU?

Note icon
Before you begin this process to install Windows 11 on unsupported machines, we recommend that you back up important data first. AOMEI Backupper is an excellent solution for this; it will keep your system safe and prevent data loss.

1. Download the Windows 11 ISO

  1. Download Windows 11 Disk Image (ISO).
  2. Open the Select Download dropdown.
  3. Select Windows 11.
  4. Hit the Download button.
  5. Click the Choose one dropdown and select your product language, then hit Confirm.Select product language to Download Windows 11
  6. Click 64-bit Download.
Note icon
The typical way to go about updating your PC to the latest update is by using the Windows 11 Installation Assistant. In this case, this doesn’t work because your system doesn’t reach the minimum system requirement.

Your browser should start downloading the image (should be around 5.1GB). While the download is ongoing, you can move on to the next step.

2. Bypass the CPU check by editing the Windows Registry

  1. Press the Windows key + R to start Run, type regedit, then click OK, or press Enter to launch the Registry Editor.
  2. Navigate to the following path: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
  3.  In the right pane, you can right-click and select New and then select the DWORD (32-bit) Value.
  4. Once the value is created, you can rename it to AllowUpgradesWithUnsupportedTPMOrCPU.
  5. You can now double click on this new value and enter 1 into the Value data field. Hit OK and close the registry editor.

Once you restart your PC and go for the next solution, the system will ignore any shortcomings regarding your CPU and even with the TPM 2.0 requirement.

3. Install Windows 11 from the ISO image

  1. After the ISO is done downloading, press Windows key + E to launch File Explorer.
  2. Locate the ISO, right-click on it and select Mount.
  3. A new virtual drive will appear on your PC. Access it and double-click on the setup.exe file to start the installation process.

After installation, you should be seeing a warning message instead of a rejection message. This message comes along with an option to install Windows 11 without losing your data.

Again, we must reiterate that you back up your important data before starting this whole process.

4. Install Windows 11 from a USB drive

Note icon
If you boot from a Windows 11 USB drive, it will clean install the OS, but the process will still go through the CPU check. Therefore, you can only run the setup from the USB drive while the system is running and after you perform the Registry tweak from Solution 2.

  1. Download the Windows 11 Media Creation Tool.
  2. Run the installer, accept the terms, then select the language and edition for the OS and hit Next.
  3. Check the USB flash drive box, then select Next.
  4. Make sure you connected the USB flash media to your PC, select it from the list and click Next.
  5. Also, make sure you have Internet connection because the app will download the Windows 11 kit and create the bootable version. Hit the Finish button when the process is completed.
  6. Now, all you need to do is to press the Windows key + E to launch File Explorer, access the Windows 11 USB bootable drive and double-click the Setup file to start the installation. 

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.

As we mentioned in the note above, it is possible to install Windows 11 on unsupported CPUs from USB, just as you’ve seen above.

However, this step can only be performed after you modify the Registry as instructed in the second solution from this guide.

That is because if you boot from the newly created bootable flash media, the system will check the CPU and won’t validate the installation.

Another way to install Windows 11 on unsupported CPU is by using Rufus, a tool that will allow you to install an image that will also get through TPM and Secure Boot checks.

Should you upgrade an unsupported CPU?

Let’s be clear about this. If you’re still yet to decide if you really want to go through with the procedure to install Windows 11 on an unsupported laptop, we recommend against doing so.

This is because Microsoft warns that there is a high tendency of experiencing bugs. They have also warned that they may eventually stop rendering security updates for unsupported PCs running this OS.

So, it might not be ideal to upgrade to the new OS if you don’t have said requirements. However, if you don’t mind a little bit of lagging here and there, feel free to follow the steps we’ve provided above.

To avoid any issues, you may also install Windows 11 on a virtual machine and test it to its full extent before loading it onto your primary machine.

It is important to note that these steps are meant to show you how to install Windows 11 on an unsupported processor. These steps only make Windows ignore the CPU requirements.

If you’re still experiencing problems with installing this recent OS, then you can take a look at our piece on how to install Windows 11 without TPM.

As you probably know, another important requirement for installing Windows 11 is for your PC to support the feature called Secure Boot.

If you get an error regarding that, we can help you with a guide on how to bypass the Secure Boot requirement and go on with the installation.
