Upgrade to Windows 11 25H2 on Unsupported Hardware

In this video I will explain how to upgrade an existing Windows 10 installation, or an earlier version of Windows 11 like 23H2, 22H2, 21H2, to the latest version of Windows 11: 25H2 when you are on unsupported hardware. In the video, we will take a look at the considerations before upgrading, explain how the upgrade works and how we can avoid the hardware limitations, followed by the actual upgrade of an unsupported Windows 10 system. This works for both Windows 10 and 11 Home and Professional.

Other scenarios:
- Upgrade from Windows 11 which is already on 24H2 on unsupported hardware: https://youtu.be/LkG87oX-aRU
