System-level icons are icons that are automatically created by the system when installing Windows, such as recycle bins, inboxes, network neighborhoods, etc. Icons are not useful to users, but they cannot be deleted directly. Open the Registry Editor, expand the HKEY_LOCAL_MACHINE\\Software\\Microsoft

Windows\\CurrentVersion\\explorer\\Desktop\\NameSpace branch, and delete the unwanted subkeys. After closing the Registry Editor and restarting your computer, you will notice that the system level icons that are not needed on the desktop have disappeared.

LOCAL_MACHINE\\System in the Registry Editor \\CurrentControlSet\\Control\\Nls\\Locale branch, Simplified Chinese users can only keep the "00000804" key value, others can be deleted mercilessly.
