Hello.
Unfortunately, the notification text for Windows Update is usually fixed and is automatically generated by the operating system based on the user's language settings. This means that you usually can't directly modify the notification text for these presets.
If you do need to customize the notification message, then you may need to find a third-party tool or write a custom script to handle the restart notification after the update. However, that this is outside the scope of standard Windows Update functionality.
Best Regards,
