You can use Folder Guard to not only protect access to files and folders, but also to the command of Windows Control Panel.

It may be not obvious, but the commands that appear in Windows Control Panel are handled by the special system files of the type "Control Panel extension" (their names have the extension .CPL) located in the C:\Windows\System32 folder. For example, the DESK.CPL file is responsible for the Display command of Control Panel, TIMEDATE.CPL – for the Date and Time command, and so on. (Some of the .CPL files are responsible for more than one command of Control Panel).

This information gives us a method of restricting access to the commands of Control Panel with Folder Guard: we simply need to restrict access to the appropriate .CPL file with Folder Guard, that would make Windows unable to use that file, and it would effectively prevent access to the appropriate command of Control Panel.

Here is the list of the common .CPL files and the Control Panel commands each of the files is responsible for:

.CPL fileControl Panel command(s)
ACCESS.CPLAccessibility Options
APPWIZ.CPLAdd/Remove Programs
DESK.CPLDisplay
FIREWALL.CPLWindows firewall
HDWWIZ.CPLAdd/Remove Hardware
INETCPL.CPLInternet settings, user accounts on Windows 95,98,Me
INFRARED.CPLInfrared
INTL.CPLRegional settings
JOY.CPLGame Controllers
MAIN.CPLFonts, Keyboard, Mouse, PC Card (PCMCIA), Printers
MMSYS.CPLSounds
MODEM.CPLModems
NCPA.CLPNetwork connections
NETCPL.CPLNetwork settings
NUSRMGR.CPLUser manager on Windows XP
ODBCCP32.CPLODBC Data Source Administrator
PASSWORD.CPLPasswords
POWERCFG.CPLPower Management
SYSDM.CPLSystem
TELEPHON.CPLTelephony
THEMES.CPLDesktop Themes
TIMEDATE.CPLDate/Time

(You may have other CPL files, or not all of the files listed above, depending on your version of Windows and other software installed on your computer).

How to use this list? Very simple:

  1. Find the command of Control Panel in the table that you want to restrict with Folder Guard;
  2. Determine the name of the .CPL file that is responsible for that command;
  3. Run Folder Guard and use its Protect – Add file command to add the desired .CPL file(s) to the main window of Folder Guard. (The .CPL files are usually located in the folder C:\Windows\System32). For example, if you want to restrict access to the Programs and Features command of Control Panel, look for the file appwiz.cpl.
  4. Now assign the No access attribute to the .CPL file you want to protect:
  5. Finally, enable the protection, as usual, and observe the effect: the command that you have restricted may still be visible in Control Panel, but when you attempt to use it, nothing should happen, the command should not work.

Please feel free to download the fully functional evaluation version and give it a try. If you don’t like it, use Windows Control Panel to uninstall it: no strings attached.
