Hello alanLiang123,
I'm John an Independent Advisor and a Microsoft user like you. I'll be happy to assist you today.
With the release of Windows version 2004 or later, Microsoft is now preventing access to the SYSTEM control panel and redirecting users to the newly updated "About" settings page. The System Applet was removed from Control Panel, this is why you can no longer access it.
Kindly check the link below for more details
