IntelliAdmin explores a service released by Microsoft that can help your computer shutdown faster. The User Profile Hive Cleanup service discussed cleans up user profiles and therefore helps reclaim and distribute system resources once a task is closed.
The idea of this program is to reclaim resources when a task is finished (memory, handles, etc). It accomplishes this by monitoring for users to log off and verifying that unused resources are reclaimed. This approach is superior as it works for any known reason that profiles do not unload and also will keep working to address new unknown issues.
