How can I force to install Windows 11 on unsupported PC?

This is a very common case as many old PC does not have TPM 2.0.

TPM (Trusted Platform Module) 2.0 is a security chip (either physical or firmware-based) that provides hardware-level encryption for:

• Secure storage of passwords, encryption keys, and certificates
• Protection against malware and hacking attempts
• BitLocker drive encryption support
• Secure boot verification

Windows 11 requires TPM 2.0 to ensure better security against modern threats like ransomware and firmware attacks.

TPM 2.0 is available 2014. This means the motherboard should be 2014 or later in order to run Windows 11. 

How to install Windows 11 on unsupported PC

1. Ensure Windows 10 is activated (21H2 or later).

2. Download the Windows 11 ISO and mount it.

3. Open Setup.exe inside the ISO.

If blocked, open Command Prompt (Admin) and run:

setup /product server

This will bypasses compatibility checks.

4. Follow the installer to install Windows 11 on this unsupported hardware without TPM 2.0 and unsupported CPU.
