From the developer:
On Windows 2000 you can benefit from this service if the application event log shows event id 1000 where the message text indicates that the profile is not unloading and that the error is "Access is denied". On Windows XP and Windows Server 2003 either event ids 1517 and 1524 indicate the same profile unload problem.
To accomplish this the service monitors for logged off users that still have registry hives loaded.
You may want to check out more software, such as AD Bulk Export, RBTray or Disk Washer, which might be similar to UPHClean.
