How to Install Windows 11 on an Unsupported PC

Category: Software Install and Setup

Windows 11 requires TPM 2.0 and Secure Boot, but you can still install it on unsupported hardware. This guide will show you how to bypass these restrictions and install Windows 11 on your PC.

Step 1: Check Your PC Compatibility

  • Download the PC Health Check tool.
  • Run the tool to check if your PC meets Windows 11 requirements.
  • If you receive an unsupported message, proceed with the following steps.

Step 2: Download Windows 11 ISO

Step 3: Create a Bootable USB

To create a bootable Windows 11 USB, use Rufus:

  1. Insert a USB drive (at least 8GB).
  2. Open Rufus and select the Windows 11 ISO.
  3. Under "Image option," choose Extended Windows 11 Installation to bypass TPM and Secure Boot.
  4. Click Start and wait for the process to finish.

Step 4: Modify Windows Registry (Bypass TPM and Secure Boot)

To skip the TPM and Secure Boot checks:

  1. Boot from the USB drive and start the Windows 11 installation.
  2. When you see the "This PC can't run Windows 11" message, 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, choose New > Key, and name it LabConfig.
  6. Inside LabConfig, create two DWORD values:
BypassTPMCheck = 1
BypassSecureBootCheck = 1
  1. Close Registry Editor and Command Prompt.
  2. Click "Back" in the installer and restart the installation.

Step 5: Complete Windows 11 Installation

Now you can install Windows 11 as usual:

  • Select your region and keyboard layout.
  • Follow on-screen instructions to set up your user account.
  • Once installed, update your drivers using Intel Driver & Support Assistant or your manufacturer’s website.

Step 6: Activate Windows (Optional)

If your previous Windows version was activated, Windows 11 should activate automatically. If not, enter your Windows 10 or 11 product key in Settings:

Settings > System > Activation

Conclusion

Installing Windows 11 on an unsupported PC is possible with simple registry tweaks and tools like Rufus. Now you can enjoy Windows 11 even if your PC doesn't meet official requirements. For further troubleshooting, visit the Microsoft Support Page.
