How to Bypass TPM and Secure Boot for Windows 11 Installation (Step-by-Step Guide)

 









How to Bypass TPM and Secure Boot for Windows 11 Installation

Windows 11 requires TPM 2.0 and Secure Boot, but many older PCs don’t support these features. If your device is blocked during installation, you can bypass the requirements using safe, tested methods.

Here are all working solutions step by step:

1. Method 1: Registry Editor Hack (During Installation)

  1. Boot your PC with the Windows 11 installation USB.

  2. When you see the error: “This PC can’t run Windows 11”, press Shift + F10 to open Command Prompt.

  3. Type regedit and press Enter.

  4. Navigate to:

    HKEY_LOCAL_MACHINE\SYSTEM\Setup

  5. Right-click Setup → New → Key → name it LabConfig.

  6. Inside LabConfig, create new DWORD (32-bit) values:

    • BypassTPMCheck → set value to 1

    • BypassSecureBootCheck → set value to 1

    • BypassRAMCheck (optional) → set value to 1

  7. Close Registry Editor, type exit in CMD.

  8. Continue installation.

Bypasses TPM 2.0 and Secure Boot instantly.

2. Method 2: Modify ISO with Rufus (Automatic)

  1. Download Rufus (latest version).

  2. Insert a USB drive (8GB+).

  3. Download Windows 11 ISO from Microsoft.

  4. Open Rufus → select ISO → click Start.

  5. A prompt appears: “Remove requirement for TPM 2.0 and Secure Boot?” → Yes.

  6. Finish the process, boot with the USB, and install Windows 11.

 Easiest method — no registry hacks needed.

3. Method 3: AppraiserRes.dll Replacement (ISO Hack)

  1. Download Windows 11 ISO.

  2. Mount the ISO → copy its contents to a folder.

  3. Go to sources folder → find appraiserres.dll.

  4. Delete it and replace it with a dummy file (blank text file renamed as appraiserres.dll).

  5. Repack ISO or create a bootable USB with Rufus.

  6. Install Windows 11 normally.

 Bypasses the compatibility checks during installation.

4. Method 4: Using Universal MediaCreationTool Wrapper

  1. Download Universal MediaCreationTool Wrapper (GitHub project).

  2. Run the script → select Windows 11.

  3. It automatically patches TPM and Secure Boot checks.

  4. Create a USB or ISO, then install Windows 11.

 Useful for advanced users who want auto-patched media.

5. Method 5: Install Windows 11 on an Unsupported PC via Upgrade

If you already have Windows 10 installed:

  1. Mount the Windows 11 ISO inside Windows 10.

  2. Run setup.exe.

  3. When the compatibility check fails, apply the Registry Hack (Method 1) before proceeding.

  4. Continue with the upgrade.

Let's you keep your apps and files without a clean install.

 Important Notes

  • Microsoft warns that bypassing TPM/Secure Boot may cause your PC to miss some security updates.

  • Always back up data before installation.

  • For long-term stability, enable TPM and Secure Boot if your hardware supports them.

 Final Words

Now you can install Windows 11 even on unsupported hardware.
