I recently became curious if the Windows Disk Cleanup tool could be automated. Could the task of performing cleanup operations on client computers be done on a routine basis without requiring user intervention?

Although I didn't find the perfect solution to complete the task, I did find a helpful alternative. The NTRegMon tool from www.sysinternals.com will monitor the registry of a system while you run the Disk Cleanup tool. (I've provided a sample of the SMS Installer script below.)

Basically, the tool accepts a number of command-line parameters to dictate what actions should to be initiated. It also modifies the appropriate registry entries and then launches the "cleanmgr" executable.

I tested the NTRegMon tool on a Windows XP SP2 system featuring Office 2003. I hope you find it as useful as I did. These are the available command-line parameters:

  • -ASTF = Active Setup Temp Folders
  • -COF = Compress Old Files
  • -CIC = Content Indexer Cleaner
  • -DPF = Downloaded Program Files
  • -ICF = Internet Cache Files
  • -MDF = Memory Dump Files
  • -MOTF = Microsoft Office Temp Files
  • -MERTF = Microsoft Event Reporting 2.0 Temp Files
  • -OSF = Office Setup Files
  • -OF = Offline Files
  • -OPF = Offline Pages Files
  • -OCF = Old Chkdsk Files
  • -RB = Recycle Bin
  • -RDCF = Remote Desktop Cache Files
  • -SLF = Setup Log Files
  • -SR = System Restore
  • -TF = Temporary Files
  • -TOF = Temporary Offline Files
  • -UBI = Uninstall Backup Image
  • -WWC = WebClient and WebPublisher Cache

Please keep in mind that this code is a proof of concept project for me. If you are interested in using this in your particular IT environment, then I highly recommend that you spend some quality time verifying that everything works as expected.
