image If you’ve ever tried using the “Disk Cleanup” function in Windows XP and been completely annoyed with how long it takes to run the “Compress Old Files” step, this article is for you. Just follow the steps below to disable the compression scanning step and have the disk cleanup complete in less than a minute (depending on your hard drive size)


  1. Open Registry Editor (Start -> Run -> regedit.exe)
  2. Navigate to:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Volume Caches\Compress Old Files
  3. Right-click on the “Compress Old Files” folder/key and choose “Export…”
  4. Save the registry file somewhere easily accessible (probably My Documents) so you can restore it if you need to later.
  5. Now, return to the “Compress Old Files” folder/key and delete all the values within it. (It should look like the image above)
  6. Close Registry Editor, open Explorer, right click on your hard drive (or other drive you wish to clean), choose “Properties”, then choose “Disk Cleanup”.

This should make things a ton faster!
