If you can't install Windows 11 on any unsupported AMD CPU, Flyby11 is a third-party tool designed to bypass Microsoft’s Windows 11 hardware checks during installation. It allows you to install or upgrade to Windows 11 even if your CPU, TPM, or Secure Boot doesn’t meet Microsoft’s official requirements by using a modified setup process that:

How to upgrade or install windows 11 on old AMD CPU

1. Download the official Windows 11 ISO from Microsoft’s website. You can choose the version you want (for example, 24H2/25H2).

2. Patch the ISO for compatibility and bypass checks。

3. Start the Windows 11 setup routine with the bypasses applied.

Always back up your system (important files or a full system image) before attempting an upgrade or clean install. 

If Flyby11 doesn't work, tools like WinUpgradeMat can create modified installation USB drives that also bypass checks. 

In addition, Microsoft offers official registry workarounds for TPM/CPU during installation, but these often still require minimal CPU support and might not allow in-place upgrades.
