Just all control panel items. Nothing more. Might be a quick and dirty fix to search for classic control panel items right from the start menu by copying the entire folder to C:\ProgramData\Microsoft\Windows\Start Menu\Programs\
Also works with custom start menu programs like StartIsBack/StartAllBack and launchers like Windows Powertoys Run.
Tested on Windows 11
Run Quck-install.bat as admin to add to start menu automatically
Similarly run Quck-uninstall.bat to remove the added items
