Failed to upgrade Windows 10 to Windows 11 23H2 on my PC

I have a good solution for upgrading Windows 10 to Windows 11 23H2. The software I recommend is Windows Update. It is the update function that comes with Windows 10, which can directly detect and install Windows 11 23H2 without downloading additional software, and it's completely free.
The simple steps for operation are as follows:

Step 1: Check if your computer configuration can meet the requirements.

Step 2: Directly tap the Windows icon on your keyboard to access the Settings window and select Update & Security.

Step 3: On the Update and Security page, tap Windows Update on the left and Check for Updates button on the right, and the system will start searching for available updates.

Step 4: The system will display Windows 11 update available or something like this prompt point to download and install it and then wait patiently for the download to complete, the system will prompt you to restart the computer to complete the installation.

Step 5: The system will automatically install the update, and the process will take 20-60 minutes. When the installation is complete, you will be taken to the Windows 11 welcome screen, where you can choose to keep your files and applications.

This is a super easy way to upgrade Windows 10 to Windows 11 23H2. However, this is not working for unsupported hardware or PC.
