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
CCleaner.ex

Explanation
CCleaner runs silently and automatically, using the current set of saved options to

e /AUTO

clean the PC. CCleaner then exits.

CCleaner.ex

CCleaner runs silently and automatically, using the current set of saved options to

e /AUTO

clean the PC. Windows then shuts down automatically..

/SHUTDOWN

Note: You cannot run /SHUTDOWN by itself. It must be preceded by /AUTO.

CCleaner.ex

CCleaner exports the cleaning rules to the INI files. Three INI files will be created

e /EXPORT

in the CCleaner's installation folder - winapp.ini, winreg.ini and winsys.ini. They
contain cleaning rules for the Application section, Registry Cleaner and the
Windows section respectively.

CCleaner.ex

CCleaner silently performs secure deletion for folders/files specified.

e /DELETE

You can specify multiple files/folders separating them with the "|" character.

"path_to_file

Example: CCleaner.exe

(s)"

/delete "D:TempSDelete*.*|D:TempSDelete*.log|D:TempSDelete*.txt|D:Te

/METHOD

mpSDeletetest.bmp"

"0-3"

The Method parameter defines the secure deletion type:
0 - 1 Pass
1 - 3 Passes
2 - 7 Passes
3 - 35 Passes
Note: You cannot use /METHOD by itself. It must be preceded by /DELETE.

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.
Command-line parameters for CCleaner Business and Technician Edition
CCleaner Business Edition and Technician Edition allow the user to perform several additional
command line operations. You can use them in batch files, scripting, shortcuts, or the Task
Scheduler to automate CCleaner operation.

Scheduling CCleaner
To schedule system cleans (for example clean the system every Friday at 10am) you will need to
manually create CCleaner entries in the Windows Task Scheduler. Please note that in order to do
this your user account needs to have Administrative privileges.
1. Open Windows Task scheduler. This is done by clicking Start > Control Panel. Then
switching to the classic view using left navigation pane. Then entering Administrative
Tools > Task Scheduler.
2. Click Task Scheduler Library.
3. From the Actions menu on the right side of the window click Create Basic Task. Create
Basic Task Wizard should open.
4. In the Name text field enter the name you’d like the task to be identified as. For
example CCleaner weekly cleans. Click Next button.
5. Select how often you’d like CCleaner to run. For example Weekly. ClickNext button.
6. Enter the date and time when you’d like the 1st clean to be performed. Then select how
often you’d like the cleaning to recur and when. ClickNext button.
7. Select Start a program option. Click Next button.
8. Click browse button and navigate to your main CCleaner.exe. It is usually located
in C:Program FilesCCleaner. Double click CCleaner (orCCleaner64 if you are using 64-bit
version of Windows).
9. In the Add arguments (optional) text field enter /auto. Click Nextbutton.
10. Check Open the Properties dialog for this task when I click Finish and
click Finish button. Properties window should open.
11. Check Run with highest privileges option and press OK button.
That’s it. All done.
Note: These instructions are intended for Windows Vista and onwards. On older operating systems
this is done in similar way but there are some differences (for example Task Scheduler is in
different location).
