You can use command-line parameters to change CCleaner’s installation behavior, or to change how CCleaner runs.
Command-line parameters for CCleaner installs
There are three parameters you can use when installing CCleaner, as follows. You can use them in batch files to automate CCleaner installations.
| Parameter | Explanation | Example |
| ccsetup.exe /S | This performs a silent install of CCleaner with default options. | ccsetup.exe /S |
| ccsetup.exe /D=<pathname> | This installs CCleaner into a different folder than the default. | ccsetup.exe /D=C:\Directory (In this example, CCleaner would be installed in the C:\Directory folder.) |
| ccsetup.exe /L=<locale> | This installs CCleaner with a language file identified by the locale ID. For a list of locale IDs, see http://support.microsoft.com/kb/221435. For a list of CCleaner’s supported languages, see this topic. |
ccsetup.exe /L=1036 (In this example, CCleaner would be installed in French.) |
Note: You can use multiple parameters by including them on the same line. For example,
ccsetup.exe /S /D=C:\CCleaner /L=1031
would install CCleaner silently in German to the C:\CCleaner folder.
Command-line parameters for CCleaner operation
There are three parameters you can use when running CCleaner, as follows. You can use them in batch files, scripting, shortcuts, or the Task Scheduler to automate CCleaner operation. For example, you could set CCleaner to run automatically every day at 3:00am.
| Parameter | Explanation |
| CCleaner.exe /AUTO | CCleaner runs silently and automatically, using the current set of saved options to clean the PC. CCleaner then exits. |
| CCleaner.exe /AUTO /SHUTDOWN | CCleaner runs silently and automatically, using the current set of saved options to clean the PC. Windows then shuts down automatically.. Note: You cannot run /SHUTDOWN by itself. It must be preceded by /AUTO. |
Note: When you run CCleaner.exe using the /AUTO parameter, CCleaner does not run the Registry cleaner. You cannot currently run the Registry cleaner through a command-line parameter
Command-line parameters for CCleaner operation pane focus
CCleaner has four ‘panes’: Cleaner, Registry, Tools, and Options. When the program is open, you can access each pane by clicking the associated icon/button at left.
If you are launching CCleaner from a command line, you can now have it open on a particular pane by specifying one of the following command-line switches:
- /CLEANER
- /REGISTRY
- /TOOLS
- /OPTIONS
If CCleaner is already open, it will display the appropriate pane. If you have more than one instance of CCleaner running, the command-line switch will only affect the topmost (if open) or left-most (if minimized) instance.
Note: CCleaner will only recognize the first pane-related command-line switch.
| Parameter | Explanation |
| CCleaner.exe /AUTO | CCleaner runs silently and automatically, using the current set of saved options to clean the PC. CCleaner then exits. |
| CCleaner.exe /AUTO /SHUTDOWN | CCleaner runs silently and automatically, using the current set of saved options to clean the PC. Windows then shuts down automatically.. Note: You cannot run /SHUTDOWN by itself. It must be preceded by /AUTO. |
Note: When you run CCleaner.exe using the /AUTO parameter, CCleaner does not run the Registry cleaner. You cannot currently run the Registry cleaner
