How Do I Reinstall Windows 11 on an Unsupported Computer?

Published in Computer Hardware 2 mins read

You can't directly reinstall Windows 11 on an unsupported computer. Microsoft has set specific hardware requirements for Windows 11, and unsupported computers won't meet these requirements.

However, you can try these workarounds:

1. Upgrade to Windows 11 with a Registry Hack

  • Warning: This method is not officially supported by Microsoft and can lead to instability or other issues.
  • Steps:
    • Back up your computer: Before making any changes, create a backup of your important data.
    • Edit the Registry: Open the Registry Editor (search for "regedit" in the Start menu) and navigate to the following key:
      • HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
    • Create a new DWORD (32-bit) Value: Right-click in the right pane and select "New > DWORD (32-bit) Value." Name it "AllowUpgradesWithUnsupportedTPMOrCPU" and set its value to "1."
    • Restart your computer: After making these changes, restart your computer.
    • Check for Windows 11 updates: Open Windows Update and check for available updates. Windows 11 should now be offered as an upgrade.

2. Install Windows 11 with a USB Drive

  • Warning: This method requires a USB drive with at least 8GB of free space.
  • Steps:
    • Download the Windows 11 ISO file: You can download the ISO file from the Microsoft website.
    • Create a bootable USB drive: Use a tool like Rufus to create a bootable USB drive with the Windows 11 ISO file.
    • Boot from the USB drive: Change the boot order in your BIOS settings to boot from the USB drive.
    • Install Windows 11: Follow the on-screen instructions to install Windows 11.

Important Notes:

  • Installing Windows 11 on unsupported hardware may result in compatibility issues.
  • Microsoft does not guarantee support for Windows 11 on unsupported computers.
  • Consider upgrading your hardware to meet the minimum requirements for Windows 11 if you encounter issues.
