Overview
On Windows 2000 the service deals with application event log event 1000 from source Userenv where the message indicates that the profile is not unloading and the error is "Access is denied". On Windows XP and Windows 2003 the equivalent events are 1517 and 1524 from source Userenv.

To accomplish this the service monitors for logged off users that still have hives loaded. When that happens the service determines which applications have handles opened to the hives and releases them. It logs the application name and what registry keys where left open. After this the system finishes unloading the profile.

System Requirements
Supported Operating Systems: Windows 2000, Windows 2000 Service Pack 2, Windows 2000 Service Pack 3, Windows 2000 Service Pack 4, Windows NT, Windows Server 2003, Windows XP

Windows Installer: To use the MSI installation package you must have Windows Installer version 2.0 installed. Otherwise you can follow the manual installation instructions from the readme provided below. Windows Installer 2.0 is included with Windows 2000 SP3 and later, Windows XP and Windows Server 2003. You can install Windows Installer 2.0 using this link Windows Installer 2.0 Redistributable for Windows NT & 2000.

NOTE: The service has not been localized but is expected to run properly on localized version of Windows. The event log messages will be shown in English.
