Are you (like most Windows users) plagued by slow system shutdowns? jkOTR visitor Andreas Springer watched the video review I did of the Fujitsu P1610 and noticed how long it took to shut down the device running Windows XP and he shot me an email pointing out that Microsoft has a fix for those long shut down times. The fix is a system service called the User Profile Hive Cleanup that once installed runs all the time and prevents the User Profile from getting muddled up in the registry. This results in much faster system shutdowns and since the fix is free I installed it and sure enough, the system shutdowns are now much faster, even on the Fujitsu which I wouldn’t think has been running long enough to get a large registry. I have subsequently installed the service on all my Windows-based computers and the shutdown now is snappy as it should be. Here’s what Microsoft has to say about the fix:
The User Profile Hive Cleanup service helps to ensure user sessions are completely terminated when a user logs off. System processes and applications occasionally maintain connections to registry keys in the user profile after a user logs off. In those cases the user session is prevented from completely ending. This can result in problems when using Roaming User Profiles in a server environment or when using locked profiles as implemented through the Shared Computer Toolkit for Windows XP.
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. When that happens the service determines which application have handles opened to the hives and releases them. It logs the application name and what registry keys were left open. After this the system finishes unloading the profile.
The User Profile Hive Cleanup service will run on WIndows 2000 and Windows XP. Those of you living on edge with Vista cannot use this service but maybe they’ve already incorporated this into Vista. A guy can dream, right?
