If you run Windows XP’s Disk Cleanup utility
regularly in order to keep your hard disk free from clutter, you
may have wished that there was a way to save your settings so you
wouldn’t have to reconfigure the utility each time you run it.
Fortunately, there is a method for saving your settings, but the
steps for doing so are undocumented. Here’s how:

  1. Access the Run dialog box by pressing
    [Windows]R.
  2. In the Open text box, type the following
    command:
    Cleanmgr /d x: /sageset:#
    In this command line, Cleanmgr is Disk Cleanup’s executable
    file name; /d x: is the letter of the drive you want to
    clean; /sageset is a special configuration command that
    tells Disk Cleanup to save the settings in the registry; and
    # is a unique number from 0 to 65,535 that designates a
    unique configuration settings file. For example, you could create
    your first configuration settings file for drive C by typing
    Cleanmgr /d C: /sageset:1 in the Open text box.
  3. When you see the Disk Cleanup Settings dialog
    box, select the check boxes next to the categories of files that
    you’d want to remove from your hard disk.
  4. Click OK to save the settings in the
    registry.
  5. To run Disk Cleanup using the saved settings,
    type the following command:
    Cleanmgr /sagerun:#

In this command line, Cleanmgr is Disk
Cleanup’s executable file name; /sagerun is a special
configuration command that tells Disk Cleanup to retrieve the saved
settings from the registry; and # is the number you used to
designate your configuration settings file.
