A. Each .cpl file represents one or more control panel applets (Start - Settings - Control Panel). Below is a list of common .cpl files and what Control Panel Applets they represent
.cpl file name | Control Panel Applets |
|---|---|
ACCESS.CPL | Accessibility options |
APPWIZ.CPL | Add/remove programs |
CONSOLE.CPL | Console |
DESK.CPL | Display |
DEVAPPS.CPL | PCMCIA, SCSI adapters and tape drives |
INETCPL.CPL | Internet |
INTL.CPL | Regional Settings |
JOY.CPL | Joystick |
MAIN.CPL | Fonts, keyboard, mouse and printers |
MLCFG32.CPL | |
MMSYS.CPL | Sounds and multimedia |
MODEM.CPL | Modems |
NCPA.CPL | Network |
NTGUARD.CPL | Dr Solomons |
ODBCCP32.CPL | ODBC |
PORTS.CPL | Ports |
RASCPL.CPL | Dial up monitor |
SRVMGR.CPL | Server, services and devices |
SYSDM.CPL | System |
TELEPHON.CPL | Telephony |
TIMEDATE.CPL | Date/time |
TWEAKUI.CPL | TWEAKUI |
UPS.CPL | UPS |
If you renames any of these files then the items they represent in the Control Panel would not be shown, e.g.
rename timedate.cpl timedate.non
would remove the date/time control panel applet.
Also, setting HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorerNoSetFolders (REG_DWORD) to 1 will hide the Control Panel, Printers and My Computer in Explorer and Start Menu. You would normally need to create this value as it does not exist by default.
