Install Windows 11 without TPM and Secure Boot

Install Windows 11 without TPM and Secure Boot! Yes, you heard it right. You can now install Windows 11 on your old PC or laptop without having the requirement of TPM and Secure Boot. When the leaked developer version was available on the internet, we saw that Microsoft has raised the minimum Windows 11 system requirements with TPM (Trusted Platform Module) and Secure Boot mandatory. The case is not different even after the release of the official preview build.

If you tried to install Windows 11 with the normal procedure, you might have faced ‘This PC can’t run Windows 11 error‘ like this:

this pc cant run windows 11

This error is even faced by several people having high-end PCs. Anyways, in this article, we’ll show you the Windows 11 TPM fix and how we installed Windows 11 without TPM 2.0 and Secure Boot on one of our old laptops. You can also follow this method on your computer if you don’t have the TPM version 2.0 or the TPM chip at all.

We have a couple of Windows 11 TPM workarounds to bypass the security requirements and install the OS on your device without any errors. So here we go.

Steps to Install Windows 11 without TPM

Step 1: Download Windows 11 ISO File

  • At first, you need to download the Windows 11 ISO file of the latest insider preview build. Head over to the link provided to get a superfast direct Google Drive download link.

Step 2: Create a Windows 11 Bootable USB

  • The next step is to create a Windows 11 bootable USB with a media creation tool. Head over to the link and refer to our guide to create one with Rufus.
  • Once you have a working bootable USB of Windows 11, you need to restart your PC and boot it from the USB you have just created with the Rufus.
  • While you restart your PC, enter BIOS using the BIOS key (depends on your PC brand and model). In our case it is F2.
  • In BIOS, enable Boot from USB option and then save and exit to boot from your Windows 11 bootable USB flash drive.

Step 3: Modify Windows Registry

  • Once you boot from the USB, you will see a message saying “This PC can’t run Windows 11” like below.
  • At this screen, you need to open the Command Prompt window by pressing Shift + F10.
  • In the command prompt window, type regedit and press enter to launch the Windows registry editor.
  • Navigate to the path HKEY_LOCAL_MACHINE\SYSTEM\Setup.
  • Click on Edit > New > Key to create a new key named LabConfig.
  • Inside the LabConfig, right-click in a blank space and click New > DWORD (32-bit) Value.
  • Then name it BypassTPMCheck.
  • Right-click on it and select Modify… option to edit the DWORD Value.
  • Now give it a value of 00000001 and click OK.
  • Similarly, you need to create another DWORD Value to bypass the Secure Boot requirement. For this, create a new one and name it BypassSecureBootCheck. Then as we did above, give it a value of 00000001 and click OK.
  • Now you have two DWORD values inside the LabConfig Key. And the screenshot will look like this:
  • Now close both the registry and command prompt windows and go back to the installation prompt screen like this.
  • Again, click the Install now button to begin the installation process. This time you will successfully bypass Windows 11 TPM and Secure Boot requirements to install the OS on your incompatible or ineligible PC.
  • You can now proceed with the normal installation process without having any issues. In the next window, it will prompt for entering the activation key. You can skip this by clicking I don’t have a product key.
  • Once you click that you will be taken to the next screen where you need to select the Windows 11 edition which you want to install on your PC.
  • On the next screen, accept the Microsoft license terms and click Next.
  • This will immediately begin the process of installation and you are done!
  • Once done, your system will restart and you will boot into the brand new Windows 11 operating system like in the screenshot below.

That’s it!

Note that this method is tried on one of our old laptops and it’s found 100% working. For the purpose of creating this guide, we tested it with the latest official preview build. This method may or may not work with upcoming builds. As of now, everything works fine and we’ve successfully bypassed the security restrictions and installed Windows 11 without TPM and Secure Boot.

Alternate Method: Create Custom Installation Media

This method of bypassing the TPM and Secure Boot requirements involves the modification of the original Windows 11 ISO file.

By this method, you can upgrade the OS by running the setup file directly from the disc image. To the following to get it done.

  • Go to the Windows 10 ISO image folder (create if you don’t have one using Rufus).
  • Navigate to the Sources folder inside the disc image file. Find the appraiserres.dll file and copy it.
  • Go to the sources folder inside Windows 11 image file and paste it there. Make sure that you replace the existing file.
  • Now using Rufus or any other media creation tool you need to recreate your custom ISO file. Once done, run the setup file again. Done!

Wrapping Up

Now that you know how to install Windows 11 without TPM 2.0 and Secure Boot security requirements. And now, it’s pretty obvious that the TPM and Secure Boot is not an inevitable thing to run Windows 11 operating system.

Out of the 2 methods, we recommend you to try the first method first. ie., editing the registry during the installation process. The method is a bit tricky but it works perfectly. The second method is just to show you another possibility to bypass the security check insisted on by Microsoft.
