How to Install Windows 11 With No TPM 2.0

Windows 10 support is ending in late 2025, prompting many users to upgrade to Windows 11. However, the TPM 2.0 requirement can be a significant hurdle. This guide outlines methods to install Windows 11 even without TPM 2.0, but proceed with caution.

Understanding TPM 2.0

The Trusted Platform Module (TPM) is a security chip enhancing system protection. TPM 2.0 specifically:

• Stores encryption keys and digital certificates securely.
• Verifies hardware integrity.
• Secures the boot process against malware.
• Supports BitLocker drive encryption.

Microsoft mandates TPM 2.0 for Windows 11 to bolster security. While many modern motherboards include TPM 2.0, older systems might rely on firmware emulation. If your system doesn't meet the requirement, here are workarounds.

Method 1: Registry Modification

This method modifies registry settings during installation to bypass the TPM check.

Step 1: Download the Windows 11 installation media from the official Microsoft website.

Step 2: Initiate the installation. You'll receive a TPM 2.0 error message.

Step 3: Open Registry Editor (regedit) as administrator.

Step 4: Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup.

Step 5: Create a new key named "LabConfig."

Step 6: Create three new DWORD (32-bit) Value entries: BypassTPMCheck, BypassRAMCheck, and BypassSecureBootCheck.

Step 7: Set the value data for each entry to "1."

Step 8: Close Registry Editor and restart the Windows 11 installation.

Method 2: Rufus Workaround

This method uses Rufus to modify the Windows 11 ISO.

Step 1: Download the latest Rufus utility. Consult the Rufus manual for guidance.

Step 2: Download Windows 10 and Windows 11 ISO files from Microsoft.

Step 3: Open the Windows 10 ISO in Rufus and extract sources\appraiserres.dll.

Step 4: Replace the appraiserres.dll file in the Windows 11 ISO with the extracted file from the Windows 10 ISO.

Step 5: Create a bootable USB drive or DVD using the modified Windows 11 ISO and install Windows 11.

Important Considerations

Method 1 may prevent Windows updates due to the lack of TPM 2.0, potentially leaving your system vulnerable. Before resorting to these workarounds, explore enabling TPM 2.0 through your BIOS settings. Using these methods means you are accepting the security risks associated with running Windows 11 without TPM 2.0.
