Install Windows 11 Without TPM 2.0

    Complete guide to bypass Windows 11 hardware requirements on older PCs

    Why Bypass TPM 2.0?

    Windows 11 requires TPM 2.0 and Secure Boot, but many capable PCs don't have these features. Microsoft enforces these requirements for security, but older hardware can still run Windows 11 smoothly. This guide shows you safe methods to install Windows 11 on unsupported hardware while understanding the trade-offs involved.

    2

    Using System Information

    Press Windows + R, type 'msinfo32' and press Enter. Look for 'Secure Boot State' and 'BIOS Mode'.

    3

    Using PC Health Check

    Download Microsoft's PC Health Check app to see all compatibility issues at once.

    Methods to Bypass TPM Requirements

    Method 1: Registry Bypass (During Installation)

    The official Microsoft-acknowledged method for bypassing TPM and Secure Boot checks during setup.

    1. 1Boot from Windows 11 installation media
    2. 2When you see the 'This PC can't run Windows 11' message, press Shift + F10
    3. 3Type 'regedit' and press Enter
    4. 4Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup
    5. 5Right-click Setup, select New > Key, name it 'LabConfig'
    6. 6Inside LabConfig, create these DWORD (32-bit) values:
    7. 7β€’ BypassTPMCheck = 1
    8. 8β€’ BypassSecureBootCheck = 1
    9. 9β€’ BypassRAMCheck = 1 (optional)
    10. 10Close Registry Editor and Command Prompt
    11. 11Click the back arrow and try again

    Method 2: Rufus (Easiest Method)

    Recommended

    Rufus automatically creates bootable USB drives that bypass all hardware checks.

    1. 1Download Rufus 4.0 or later from rufus.ie
    2. 2Download Windows 11 ISO from Microsoft
    3. 3Insert a USB drive (8GB minimum)
    4. 4Open Rufus and select your USB drive
    5. 5Click SELECT and choose your Windows 11 ISO
    6. 6Click START and wait for the dialog
    7. 7Check 'Remove requirement for 4GB+ RAM, Secure Boot and TPM 2.0'
    8. 8Check 'Remove requirement for an online Microsoft account' (optional)
    9. 9Click OK and wait for the process to complete
    10. 10Boot from the USB and install normally

    Method 3: In-Place Upgrade Bypass

    Upgrade from Windows 10 to Windows 11 on unsupported hardware.

    1. 1Download Windows 11 ISO from Microsoft
    2. 2Mount the ISO by double-clicking it
    3. 3Open Command Prompt as Administrator
    4. 4Navigate to the mounted drive (e.g., 'D:')
    5. 5Run: setup.exe /product server
    6. 6This tells the installer you're upgrading a server (bypasses checks)
    7. 7Follow the installation wizard normally
    8. 8Your files and apps will be preserved

    Method 4: Modified ISO

    Create a custom Windows 11 ISO with checks permanently removed.

    1. 1Download the official Windows 11 ISO
    2. 2Extract the ISO contents to a folder
    3. 3Navigate to the 'sources' folder
    4. 4Find and edit 'appraiserres.dll' (replace with Windows 10 version)
    5. 5Or delete 'appraiserres.dll' entirely
    6. 6Recreate the ISO using tools like DISM or AnyBurn
    7. 7Use the modified ISO for installation

    Important Warnings & Considerations

    Update Limitations

    Microsoft warns that unsupported PCs may not receive all updates. However, in practice, most updates still install normally.

    Security Trade-offs

    TPM 2.0 provides hardware-level security for BitLocker, Windows Hello, and credential storage. Without it, these features may not work or be less secure.

    No Microsoft Support

    Microsoft won't provide support for Windows 11 on unsupported hardware. You're on your own for troubleshooting.

    Watermark Possibility

    Some users report a 'System requirements not met' watermark. This can usually be removed with registry tweaks.

    After Installation

    1

    Activate Windows

    Use your existing Windows 10 key or purchase a Windows 11 key. Digital licenses from Windows 10 usually transfer automatically.

    2

    Install Drivers

    Windows Update should find most drivers. Check your manufacturer's website for any missing drivers.

    3

    Check for Updates

    Run Windows Update to get the latest security patches and feature updates.

    4

    Remove Watermark (If Present)

    Open Registry Editor, navigate to HKEY_CURRENT_USER\Control Panel\UnsupportedHardwareNotificationCache, set SV2 to 0.
