To hide or show any specific Control Panel applet in Windows.
A: For All Windows Versions except Windows 95, 98 & Me
1. Type regedit in RUN dialog box and press Enter. Now go to:
HKEY_CURRENT_USER\Control Panel\
OR
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\
2. Under this key create a new key with the name don't load , so the new path will be:
HKEY_CURRENT_USER\Control Panel\don't load
OR
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\don't load
3. Now in right-side pane, create new String value. Set its name to the file name of the applet which you want to hide, e.g. if you want to hide Display applet then set its name to Desk.cpl now set its value to no to hide it. If you want to show it again, either set its value to yes or simply delete the String value.
To use the above mentioned method, you'll need to know the .CPL file name of the desired applet. You can search for .CPL in Windows Search or you can use help of following list which contains .cpl file names of almost all default Control Panel applets:
Access.cpl Accessibility
Appwiz.cpl Add or Remove Programs
Bthprops.cpl Bluetooth Devices
Desk.cpl Display
Hdwwiz.cpl Add New Hardware
Inetcpl.cpl Internet Options
Intl.cpl Regional and Language Options
Joy.cpl Game Controllers
Keymgr.cpl Stored User Names and Passwords
Liccpa.cpl Licensing
Main.cpl Mouse
Mlcfg32.cpl Mail
Mmsys.cpl Sound and Audio Devices
Ncpa.cpl Network Connections
Nusrmgr.cpl User Accounts
Nwc.cpl Netware client connectivity
Odbccp32.cpl ODBC Data Source Administrator
Powercfg.cpl Power Options
Sysdm.cpl System
Telephon.cpl Phone and Modem Options
Timedate.cpl Date and Time
Sapi.cpl Speech
Wuaucpl.cpl Automatic Updates
Wscui.cpl Security Center or Action Center
B: For All Windows Versions except Windows 95, 98 & Me
1. Type regedit in RUN dialog box and press Enter. Now go to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies
2. Look for a key "Explorer" under it. If its not present, then create a new one and give it name Explorer.
3. Select "Explorer" key and in right-side pane, create a new DWORD value DisallowCpl and set its value to 1
4. Now create another new key under Explorer key with the name DisallowCpl so the new path will be:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ Explorer\DisallowCpl
5. Select "DisallowCpl" key and in right-side, create new String value with name 1 and set its value to the applet name which you want to hide.You don't need to use the .cpl file name of applet in this method. You have to put the applet label which you see in Control Panel.
e.g., If you want to hide AutoPlay applet, then create a new String value, give it name 1 and set its value to AutoPlay. If you want to hide more applets, then simply create more String values with names 2, 3 and so on and set their values to the applet label.
C: For All Windows Versions except Windows 95, 98 & Me
In this method, you'll tell Windows which applets should be visible and Windows will automatically hide the rest.
Its useful when you want to show a few specific applets and want to hide remaining applets. So you just need to create a few String values to tell Windows which applets you want to show. It'll save your valuable time.
1. Type regedit in RUN dialog box and press Enter. Now go to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies
2. Look for a key "Explorer" under it. If its not present, then create a new one and give it name Explorer.
3. Select "Explorer" key and in right-side pane, create a new DWORD value RestrictCpl and set its value to 1
4. Now create another new key under Explorer key with the name RestrictCpl so the new path will be:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ Explorer\RestrictCpl
5. Select "RestrictCpl" key and in right-side, create new String value with name 1 and set its value to the applet name which you want to show.You don't need to use the .cpl file name of applet in this method. You have to put the applet label which you see in Control Panel.
e.g., If you want to show AutoPlay applet, then create a new String value, give it name 1 and set its value to AutoPlay. If you want to show more applets, then simply create more String values with names 2, 3 and so on and set their values to the applet label.
Now Windows will only show the applets which you mentioned in String values, other applets will be hidden.
D: For Windows 95, 98 & Me
1. Open "%windir%\Control.INI" file. Where "%windir%" denotes Windows folder which is present in system drive where Windows is installed.
2. You'll see a line saying [don't load] in the file. If you can't find it, then create a new line at last.
3. Now under this line, you can set .CPL file name of your desired applet which you want to hide in following format:
filename.cpl=no
e.g.,
If you want to hide Display applet, then the syntax will be:
desk.cpl=no
You can create similar lines for other applets which you want to hide. The .CPL file name can be obtained from the list mentioned in A.
