用户配置文件蜂巢清理服务

 

Brief Description

A service to help with slow log off and unreconciled profile problems.

简介：

能够解决注销关机慢以及不稳定的用户配置文件问题的服务

Overview

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.

UPHCleanup 服务能够确保在用户注销关机之后能够完全中止用户的会话。偶尔有些系统进程和应用程序在用户注销关机之后依然与注册表键值保持着连接。因为这些原因用户会话将在系统完全关闭前被保护

 

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.
