TypeControl panel

Control Panel is a component of

user accounts, changing accessibility
options, and accessing networking settings. Additional applets are provided by third parties, such as audio and video drivers, VPN tools, input devices, and networking tools.

Overview

Control Panel has been part of Microsoft Windows since

shortcuts
to various applets such as Add or Remove Programs and Internet Options. Physically, these applets are stored as .cpl files. For example, the Add or Remove Programs applet is stored under the name appwiz.cpl in the SYSTEM32 folder.

In

Windows ME and XP, the Control Panel home screen was changed to present a categorized navigation structure reminiscent of navigating a web page. Users can switch between this Category View and the grid-based Classic View through an option that appears on either the left side or top of the window. In Windows Vista and Windows 7
, additional layers of navigation were introduced, and the Control Panel window itself became the main interface for editing settings, as opposed to launching separate dialogs.

Many of the individual Control Panel applets can be accessed in other ways. For instance, Display Properties can be accessed by right-clicking on an empty area of the desktop and choosing Properties. The Control Panel can be accessed from a command prompt by typing control; optional parameters are available to open specific control panels.[2]

On

Metro-style app platform. Some functions, particularly the ability to add and remove user accounts, were moved exclusively to this app on Windows 8 and cannot be performed from Control Panel.[3][4]

As of the October 2020 update to Windows 10, opening up the System applet in Control Panel will now redirect users to the About section of the Windows 10 Settings application. The page for the applet in Control Panel still exists even in current versions of Windows 10, however Microsoft is actively trying to block shortcuts and third party applications that could have been used to get into the old System page, which could potentially lead to a permanent removal of said page from Control Panel in future versions of Windows.[citation needed]

List of Control Panel applets

The applets listed below are components of the

registry
under the following keys:

  1. HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\Cpls
    This contains the string format locations of all .cpl files on the hard drive used within the control panel.
  2. HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ControlPanel\Namespace
    This contains the location of the
    CLSID variables for all the panels not included as cpl files. These are commonly folders or shell applets, though Windows Vista
    allows physical programs themselves to be registered as well. The CLSID then allows items such as the icon, infobox and category to be set and gives the location of the file to be used.

The control panel then uses these lists to locate the applets and load them into the control panel program (control.exe) when started by the user. In addition to using the control panel, a user can also invoke the applets manually via the command processor. For instance, the syntax "Control.exe inetcpl.cpl" or "control.exe /name Microsoft.InternetOptions" will run the internet properties applet in Windows XP or Vista respectively. While both syntax examples are accepted on Windows Vista, only the former one is accepted on Windows XP.[5]

Standard applets

(Renamed "Ease of Access Center" in Windows Vista and later)
