If CLEANMGR is run without /sageset or /sagerun, it will start by calculating how much disk space could be saved. This makes the process slower to startup. By default only the Downloaded Program Files and Temporary Internet Files will be selected.

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. When necessary CLEANMGR can take ownership of the files before deleting them.

To enable Cleanmgr on older servers of Windows Server, open Server Manager and choose Add feature, then select "Desktop Experience"
After running cleanmgr on a server you may want to disable "Desktop Experience" again.

Application Data

The user's 'Application Data' folder is not available for cleanup in the above list. Many files in Application Data hold system data that should not be deleted. However if you have an application that leaves a significant number of temporary/junk files in App Data, these can be selectively removed from a roaming profile with a VBScript like this.

Recent files

The 'User Profile/Recent Items' folder can contain many more shortcuts than are useful. A very large number of these can affect logon/logoff times. To clear out the shortcuts:

CD %userprofile%\AppData\Roaming\Microsoft\Windows\Recent
Echo y| del *.*

Close Locked files by restarting Windows Explorer

Save the following batch script:
@Echo off
Taskkill /f /im Explorer.exe
Start Explorer.exe
Exit

Then to restart Windows Explorer, just run the batch file.

Registry

Registry settings for CLEANMGR are held in:
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches]

Here are a set of registry entries to turn on a typical selection of cleanmgr options, these can be used with REG or Regedit to pre-populate the regisitry as a scriptable alternative to running /SAGESET

Log files for CLEANMGR are stored in:
C:\Windows\System32\LogFiles\setupcln\

Examples

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

 CLEANMGR /sageset:64

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
