How to update Windows 11 22H2 to 24H2 on unsupported PC?

It becomes more challenging to upgrade Windows 11 on an unsupported hardware because of new hardware requirements. You can use the DISM command to do that.

1. Get the latest Windows 11 24H2 ISO file from Microsoft official website.

2. Use the official tool to make the ISO into a USB boot disc (select USB device→ISO file→Partitioning mode select GPT+UEFI).

3. Open Command Prompt as administrator (right-click Start menu → Windows Terminal → Administrator).
Execute the following command to repair the system:

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
DISM /Online /Apply-Package /PackagePath:C:\sources\install.wim /Index:1

4. Ensure that the computer is connected to the Internet (you need to download the update package). Enter the following command to force the deployment of the 24H2 system files:

5. Wait for the progress to complete (may take more than 30 minutes depending on the network speed).

6. When finished, type exit to exit the command prompt and the system will reboot automatically.

After entering the Windows installation interface: Select language → Next → 'Keep files and upgrade'.

This is a very simple to upgrade or update Windows 11 22H2 to 24H2 on unsupported PC. Please backup your data first!
