Help Needed: Install Windows 11 Without TPM on My PC

Copper Contributor

I am trying to upgrade my Windows 10 PC to Windows 11 as Microsoft asks me to do that from time to time. I downloaded the Windows 11 Installation Assistance but it tells me that this PC can't run this version of Windows 11.

 

Later, I downloaded the PC Heather Check app and it says my PC is missing TPM. I'm really eager to upgrade, but I'm stuck at this roadblock and not sure how to proceed. Has anyone successfully installed Windows 11 without TPM?

 

If so, could you please share the steps or any workarounds you used? I would greatly appreciate any suggestion on how to bypass this requirement. I'm open to trying different methods or tools to make this upgrade possible.

It is now 2024 and there are dozens of ways to help you install Windows 11 without TPM and Secure Boot, even for very old PCs. I managed to install Windows 11 on a 10-year old ThinkPad laptop (No TPM & Secure Boot) with the help of this step-by-step guide: https://www.tekgit.com/install-windows-11-without-tpm

If your PC doesn't have a compatible TPM chip, you can still install Windows 11 without TPM, You can disable secure boot:

  • Restart your PC and press the key to access the BIOS settings (usually F2, F12, or Del).
  • Navigate to the "Boot" or "Secure Boot" section and disable Secure Boot.
  • Save the changes and exit the BIOS settings.
  • Restart your PC again and try running the Windows 11 installation media (USB drive or ISO file).

@elliot-williamsOne simple trick is by editing the Registry during Windows 11 installation.

 

  1. Boot from the Windows 11 USB drive.
  2. When you see the "This PC can't run Windows 11" message, press Shift + F10 to open the Command Prompt.
  3. Type regedit and press Enter to open the Registry Editor.
  4. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup.
  5. Right-click on Setup and select New > Key. Name it LabConfig.
  6. Right-click on LabConfig and select New > DWORD (32-bit) Value. Name it BypassTPMCheck.
  7. Double-click on BypassTPMCheck and set the value to 1.
  8. Create another DWORD (32-bit) value named BypassSecureBootCheck and set the value to 1.
  9. Close the Registry Editor and Command Prompt.
  10. Continue with the installation.

 

At this time, you won't see any error and you can proceed to install Windows 11 on a PC without TPM.  However, this is not an user friendly solution, especially for newbies.

Understand that you want to upgrade to Windows 11 wtihout TPM. Microsoft does have some hardware requirements, including TPM 2.0, which can be a challenge for many older computers.

 

However, there are some unofficial ways to install Windows 11 without TPM, but this involves modifying the installation media, which can be risky. For example, future Windows updates may detect this bypass and may cause compatibility or security issues. If you are willing to try, I can provide a rough guide of the steps, but please be aware that doing so may violate Microsoft's terms of use and may have an impact on the security of your system.

 

If you decide to proceed, be sure to back up important data in case anything unexpected happens. Here are the rough steps:

 

Step 1. First, you need to download the ISO file of Windows 11 from the official Microsoft website.

Step 2. Modify the ISO file: Using some tools (such as Rufus or other third-party software), you can disable the TPM check when creating the installation USB. Tools such as Rufus provide an option to bypass the TPM check when creating the boot disk.

Step 3. Make a bootable USB: Use the modified ISO file and burn it to a USB drive via Rufus.

Step 4. Plug the USB into your PC, reboot, enter BIOS, set to boot from USB, and follow the on-screen instructions to install.

 

Again, this method may bring risks, including system stability and security issues. If your PC is mission-critical or data-sensitive, it is recommended to consider upgrading the hardware or using a device that meets the official Windows 11 requirements.

I remember one time, I had a friend who wanted to install windows 11 without tpm 2.0 and secure boot. His situation was similar to yours, his computer did not have TPM 2.0, and he also received an upgrade push from Microsoft.

 

He first tried to find out if he could enable TPM in the BIOS, but had no luck. Then he considered replacing the hardware, but felt that the cost was a bit high and not worth it. Finally, he decided to use a tool like Win-BootMateto try to create an installation media that bypassed TPM check. The process was a bit complicated, and he was a little worried about what problems he might encounter, such as future updates might be affected.

 

In the end, he decided to take a risk and followed the online tutorial step by step, and finally installed it successfully. Although the system ran smoothly, he was a little nervous every time he updated, worried that it would be incompatible one day. He later told me that if it was really necessary to upgrade the hardware, or considering long-term stability and security, he might choose to buy a new computer, or at least upgrade the motherboard.

I can tell you about a time I helped a user set up a virtual machine to install windows 11 without tpm 2.0 and secure boot. This user was in a similar situation to you, his computer also failed the TPM 2.0 check, but he was eager to try out the new features of Windows 11. He decided to use a virtual machine to bypass TPM check.

 

First, we chose VMware Workstation and VirtualBox, both of which are very popular virtual machine software that support most operating systems. To ensure everything goes smoothly, we downloaded the official ISO file of Windows 11.

 

  1. Open VMware and create a new virtual machine.
  2. Select Install Disc Image File (ISO) and browse to the Windows 11 ISO file we downloaded.
  3. As recommended, sufficient memory and processor resources were allocated.
  4. Some adjustments to network and display settings were made to ensure the virtual machine runs smoothly.

During the installation process, Windows 11 installed smoothly in the virtual environment because the virtual machine itself simulates the required hardware environment, including TPM. After the installation is completed, the user can start exploring Windows 11, and all new features can be used, just like running in a real environment.

 

Although the system response speed may not be as fast as on a physical machine, especially when running some resource-intensive applications, but overall, the experience was successful. The user was very satisfied with it because he did not need to change any hardware to experience Windows 11.

Keep in mind that installing Windows 11 without TPM may not provide optimal security features or support. Additionally, Microsoft may not officially support this workaround, and it may affect your system's stability or functionality.
If your PC is critical or handles sensitive data, it's recommended to upgrade your hardware or use a device that meets the official Windows 11 requirements.
