/sageset and /sagerun cannot be combined in a single command.

If CLEANMGR is run without /sageset or /sagerun, it will start by calculating how much disk space could be saved. This makes the process much slower to run.

Some cleanup options require elevation, when run without elevation the GUI will include an option [Clean up System Files] which will relaunch CLEANMGR in Elevated mode.


Choose a set of options for cleanup (this will display the GUI) and Save as settings group #64:

 CLEANMGR /sageset:64

Temporary Internet Files *
Temporary Setup Files
Downloaded Program Files *
Old Chkdsk Files
Recycle Bin *
Temporary Files
Temporary Offline Files
Offline Files
Compress Old Files
Catalog Files for the Content Indexer
System files: Debug/chkdsk/Installer/Memory dump/Windows update/error reporting logs.

Items in bold can appear in more than one drive, the items marked with * can be viewed in the GUI.

Run the saved settings group #64

 CLEANMGR /sagerun:64

To run Disk Cleanup this way regularly, you can create a shortcut which can be run from the Windows Startup folder or via a regular schedule. To run the saved settings group #64

%systemroot%\system32\cmd.exe /c CLEANMGR /sagerun:64

Application Data

Many files in Application Data hold system data that should not be deleted, however some applications do leave files which you can delete from a roaming profile, these can be selectively removed with a VBScript like this.

Recent files

The 'User Profile/Recent' folder (for Start, Documents) can contain many more shortcuts than are set to display in the GUI. A very large number of these can affect logon/logoff times.
To clear out the shortcuts:

cd %userprofile%\Recent
echo y| del *.*

Close Locked files by restarting Windows Explorer

Close all applications
Open a command prompt
taskkill /im explorer
This should kill explorer and bring up a logout/shutdown dialogue box.
Simultaneously press CTRL+SHIFT+ALT.
While you keep these keys pressed, click [Cancel] in the Shut Down Windows dialog box.
In the command prompt window, you should now be able to delete the locked files.
At the command prompt, type explorer, and press ENTER to restart Windows Explorer.

To enable Cleanmgr on Windows 2008, open Server Manager and choose Add feature, then select "Desktop Experience"
After running cleanmgr on a server you will probably want to disable "Desktop Experience" again (or use this script.)
When necessary cleanmgr can take ownership of the files before deleting them.

Registry settings for CLEANMGR are held in:
