Upgrade to Windows 11 23H2 from Windows 11 22H2 or 21H2 on Unsupported Hardware

In this video, I will explain how to upgrade to Windows 11 23H2, starting from an existing Windows 11 22H2 or 21H2 Home or Pro installation on unsupported hardware. Since 23H2, there are two options to do this. Either through Windows Update or by using the Windows 11 23H2 ISO. The idea of upgrading your current installation is to keep all applications and data. In the video, I will be performing the upgrade on a PC which does not have a supported CPU, no TPM nor secure boot.
