If you want to install Windows 11 on unsupported PCs you need to add the following registry value and reboot
Before installing Windows 11 on unsupported Hardware be aware that any security updates are no longer guaranteed or supported. For security reasons it is better to have at least a TPM 2.0 Chip and better also an up-to-date processor installed!

powershell "start regedit -Verb runAs"
and press [Enter]
Alternatively Press the windows key and enter regedit, right click it and select “Run as Administrator”)
Add the registry value using powershell
be sure to run powershell with elevated rights (right click –> “Run as Administrator”)
New-ItemProperty -Path "HKLM:\SYSTEM\Setup\MoSetup" -Name "AllowUpgradesWithUnsupportedTPMOrCPU" -Value 1 -PropertyType DWORD -Force
