How to Install Windows 11 With No TPM 2.0

Quick Tips

• Before modifying the registry, make sure to create a backup by saving the complete registry file.
• Offload your important data before reinstalling Windows.
• This type of installation comes with downsides, so only use it as last resort.

With Windows 10 support slowly timing out by the end of 2025 and limited extension options available, most users will eventually have to pull the trigger and upgrade to Windows 11. But when you do try to upgrade, you might find that you’re missing the vital TPM 2.0 prerequisite. If you can’t enable it, you’re stuck with Windows 10.

Or are you? Here’s how to install Windows 11 with no TPM 2.0.

What Is TPM 2.0?

TPM (Trusted Platform Module) is a specialized chip on your computer’s motherboard that provides hardware-based security functions. TPM 2.0 specifically performs several critical security roles:

• Encryption key storage: Securely stores encryption keys, passwords, and digital certificates.
• Hardware authentication: Verifies that your hardware hasn’t been tampered with.
• Secure boot process: Helps protect your system from rootkits and boot-level malware.
• BitLocker support: Enhances the security of Microsoft’s drive encryption technology.

Microsoft requires TPM 2.0 for Windows 11 to establish a stronger security baseline across all Windows devices, reducing vulnerability to increasingly sophisticated cyber threats.

However, most motherboards don’t actually come with hardwired chips for TPM 2.0. Instead, many manufacturers provide firmware that the OS sees as TPM, with similar functionalities. This is typically true for motherboards made in the previous decade, so even older PCs should have the function in one way or another.

But even older PCs that still meet the minimum hardware requirements might struggle with this, as it’s solely up to the motherboard. Thus, we come to the workaround.

Method 1. How to Install Windows 11 With no TPM 2.0 With Registry Changes

The process for installing Windows this way hinges on changing the registry files that check for the TPM version, which is done during the installation itself.

Step 1. Go to the official Windows download page and select “Download Now” (choosing the first option above the “Installation Media” section).

Step 2. When prompted, start the installation process. You should receive an error message saying that your PC can’t install Windows 11.

Step 3. Open the Registry Editor (you can search for it under “regedit”). Make sure to “Run as administrator.”

Step 4. Go to the location “HKEY_LOCAL_MACHINE\SYSTEM\Setup.” You can paste this in the address box at the top of the navigation bar.

Step 5. Right-click on “Setup” and choose “New” then “Key.” Name the key “LabConfig.”

Step 6. Right-click on “LabConfig,” choose “New” and select “DWORD 32-bit.”

Step 7. Create values for “BypassTPMCheck,” “BypassRAMCheck,” and “BypassSecureBootCheck.” Set the value for all of these to 1 by right-clicking and selecting “Modify,” then entering the value “1.”

Step 8. Close the Registry Editor and restart the installation process from Microsoft’s page.

Method 2. Rufus Workaround

This method uses the installation media to fool the PC into thinking it’s installing Windows 10, which doesn’t have the TPM 2.0 requirement.

Step 1. Go to Rufus and download the latest version. Then, you’ll need to get acquainted with its user manual.

Step 2. Go to the Windows download page and locate the ISO downloads for Windows 10 and Windows 11.

Step 3. Open the Windows 10 ISO with Rufus and extract the file “sources\appraiserres.dll/”

Step 4. Put that file in the Windows 11 ISO, replacing its own file with it.

Step 5. Create a bootable USB or DVD using the modified ISO file for Windows 11, then install Windows with it.

Important Notes

With Method 1, your PC likely won’t receive any Windows updates, as the lack of a TPM chip will disable them. That means that you might be running an unsecured version of Windows 11. So, before trying to brute-force the installation, you might want to see if you can enable TPM on your PC via BIOS.
