How to Install Windows 11 without TPM / with unsupported CPU

Much controversy has come from Microsoft’s decision to restrict Windows 11 to machines that support TPM 2.0, with the company itself even seeming uncertain about the move.

The upgrade or installation of Windows 11 also fails on other unsupported hardware such as certain older CPUs.

We have already shown you how to check if your PC has a TPM chip. Today, we’ll be teaching you how to install Windows 11 without TPM 2.0 chip or how to install it if your PC has only TPM 1.2 or an unsupported CPU. If you are unsure about the Windows 11 processor requirements, please check the official lists of Intel and AMD CPUs that will work with Windows 11 at the end of this article.

What is TPM?

TPM stands for Trusted Platform Module, which may not mean much to you alone. Essentially, TPM is a security module typically soldered onto the motherboard in the form of a chip. It acts as a cryptographic processor and offers a hardware-based approach to generating hashes and storing cryptographic keys, biometric data, user data, and more.

Rooting the cryptography in hardware makes it all but impossible for attackers to tamper with and access this data, protecting against malware, ransomware, and sophisticated nation-state attacks.

Is it safe to install Windows 11 without TPM 2.0?

Despite what Microsoft’s Windows 11 compatibility tool may tell you, installing Windows 11 without TPM is quite simple. All it requires is putting a few registry entries or using a script based tool to activate a Windows 11 TPM 2.0 bypass.

Before you do so, however, you should consider that TPM 2.0 is used to power many of Windows 11’s security features. This includes measured boot, Windows Hello, SecureBIO, WD System Guard, and Device Health Attestation. When you run Windows 11 without a TPM chip, you won’t have access to these features and may be putting your data more at risk as a result.

If possible, then, we recommend that you install a discrete TPM 2.0 module or wait and upgrade your hardware. It’s likely Windows 11 will only rely on TPM more in the future and we can’t guarantee that Microsoft won’t disable this bypass at a later point.

Windows 11 TPM 2.0 Bypass

If you really can’t do the above or just want to take the new OS for a test drive, however, this is how you install Windows 11 on unsupported hardware. You can either tweak the installation routine yourself (methods 1 & 3), use a wrapper-tool for Microsoft´s Media Creation Tool to get an ISO/USB without the Windows 11 TPM-check (method 2) or apply a Windows 11 TPM 2.0 bypass for upgrading a running Windows 10 system to Windows 11 (method 4).

How to install Windows 11 without TPM 2.0 / TPM 1.2

As mentioned, installing Windows 11 without TPM requires a few registry entries. The easiest way to bypass the Windows 11 TPM check this is to try to install Windows 11 via an ISO or the Insider program, then follow the steps below if you get a “This PC can’t run Windows 11” message. 

If you see the message “This PC does not meet the system requirement”, minimize the installer, go to registry, edit the entries, then go back to the installer, Press back button once, and continue. If you prefer to do this the easy way you can avoid the standard setup/installation provided by Microsoft and use one of the methods shown after this one.

  1. Press Shift + F10 to open Command Prompt and run the “regedit” command

    Windows 10 - Windows Setup - Can´t run Windows 10 - Command Prompt

  2. Add a new key in the “Setup” key

    In the Registry Editor, navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\Setup. Right-click on the “Setup” folder in your sidebar and select “New > Key”.

    Windows 10 - Windows Setup - Can´t run Windows 10 - Command Prompt - Registry Editor - Navigate to - Setup - New Key

  3. Name the key “LabConfig” and add a new DWORD

    After you name your folder, you can create the DWORD by right-clicking in any blank space in the main pane and selecting “DWORD (32-bit) Value”.

    Windows 10 - Windows Setup - Can´t run Windows 10 - Command Prompt - Registry Editor - Navigate to - Setup - LabConfig - New DWORD

  4. Name the value “BypassTPMCheck” and set the value data to 1.

    It’s important the capitalization and spelling are exactly the same. You can modify the value data by double-clicking your new DWORD and changing the “Value data” text box. Press “OK” when you’re done to save the changes.

    Windows 10 - Windows Setup - Can´t run Windows 10 - Command Prompt - Registry Editor - Navigate to - Setup - LabConfig - New DWORD - BypassTPMCheck - 1 Value

  5. Create another DWORD called “BypassRAMCheck”

    Again, make sure the capitalization and spelling is exactly the same as above.

    Windows 10 - Windows Setup - Can´t run Windows 10 - Command Prompt - Registry Editor - Navigate to - Setup - LabConfig - New DWORD

  6. Change the value data to 1

    Remember, you can access the value data field by double-clicking on the “BypassRAMCheck” key. Press “OK” to apply it.

    Windows 10 - Windows Setup - Can´t run Windows 10 - Command Prompt - Registry Editor - Navigate to - Setup - LabConfig - New DWORD BypassRAMCheck - 1 Value

  7. Create a new DWORD called “BypassSecureBootCheck”

     

    Windows 10 - Windows Setup - Can´t run Windows 10 - Command Prompt - Registry Editor - Navigate to - Setup - LabConfig - New DWORD

  8. Change the value data of SecureBootCheck to 1 and press “OK”

     

    Windows 10 - Windows Setup - Can´t run Windows 10 - Command Prompt - Registry Editor - Navigate to - Setup - LabConfig - New DWORD - BypassSecureBootCheck - 1 Value

  9. Close the Registry Editor and press the back button on your Windows 11 setup

    You’ll find the back button in the top-left corner.

    Windows 10 - Windows Setup - Can´t run Windows 10 - Open Arrow

  10. Install Windows 10 on your unsupported hardware

    You can now go through the setup process as normal. Your installer should no longer tell you your PC is incompatible.

How to auto-create a Windows 11-ISO without TPM-check for installation

You can use Microsoft´s Media Creation Tool with the script-based tool Universal MediaCreationTool wrapper (Universal MCT wrapper) to automatically download Windows 11 from Microsoft´s servers and create ISO-files where the TPM check has been removed. If you want to use this ISO to upgrade Windows 10 to Windows 11 dynamically from a running system, you will additionally need to activate the TPM bypass shown in method 4 below.

  1. Download and unzip Universal MCT wrapper

    Download Universal MCT wrapper from GitHub, unpack the ZIP-file and run “MediaCreationTool.bat”. If you want to learn more about the project, you find everything here.

  2. Click on “11” to select “Windows 11”

    Universal MCT wrapper - Select Windows 11

  3. Choose “Create ISO” or “Create USB” based on your preference.

    “Create USB” will automatically create a bootable USB-stick which can be used for a fresh installation of “Windows 11”.

  4. Wait until the Media Creation Tool has finished downloading Windows 11

    After the download of Windows 11 has been finished, the Media Creation Tool will close automatically and Universal MCT wrapper will create an ISO/USB which allows installing Windows 11 without TPM.

  5. Wait for Universal MCT wrapper to finish

How to upgrade to Windows 11 with unsupported CPU / without TPM 1.2

If your PC fails to upgrade to Windows 11 because of an unsupported CPU and/or that your device only has TPM 1.2 instead of TPM 2.0, you can fix that quickly. Just apply the following registry-tweak to add a bypass for unsupported CPU and TPM 1.2.

  1. Open Regedit

    Windows 10 - Search - Regedit

  2. Navigate to folder and check for existing DWORD

    Use the address bar to navigate to “HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup” and check if the DWORD “AllowUpgradesWithUnsupportedTPMOrCPU” is located there. If it is missing, right-click in the right pane, select “New > DWORD (32-bit) Value”, and name the new DWORD “AllowUpgradesWithUnsupportedTPMOrCPU”.

    Windows 10 - Regedit - HKEY_LOCAL_MACHINE SYSTEM Setup MoSetup

  3. Edit DWORD “AllowUpgradesWithUnsupportedTPMOrCPU”

    Double click on “AllowUpgradesWithUnsupportedTPMOrCPU”, type “1” in “Value data” and save with “OK”.

How to upgrade to Windows 11 without any TPM (TPM 2.0 / TPM 1.2) 

If you want to directly upgrade Windows 10 to Windows 11 without a TPM 2.0 chip, you can use the wrapper tool from the previous step to activate a bypass with a simple click. This method is also needed if you run the Windows 11 upgrade from a previously created ISO created with method 2.

  1. Run the Windows 11 TPM 2.0 bypass

    Double-click on “Skip_TPM_Check_on_Dynamic_Update_v2.cmd” as admin to remove the TPM-check for updates. If this does not work, you can try alternatively “Skip_TPM_Check_on_Dynamic_Update_v1.cmd”.

    Skip_TPM_Check_on_Dynamic_Update_v2.cmd

  2. Wait for confirmation

    If you see a PowerShell window popping up with a green bar stating “Skip TPM Check on Dynamic Update [Installed]…” the TPM 2.0 bypass has been activated and you should be able to upgrade from Windows 10 to Windows 11 without TPM 2.0. Running the respective CMD-script again will re-activate the TPM-check.
