解决配置文件卸载问题
当您从运行 Microsoft Windows Server 2003、Windows XP、Windows 2000 或 Windows NT 4.0 的电脑登出时，可能会遇到以下症状：‧ 用户配置文件无法卸载。
‧ 漫游配置文件无法协调。
‧ 达到注册表大小限制 (RSL)。
‧ 花费了很长时间进行登出，但收到如下资料：
正在保存设置…。
此外，还可能在应用程式事件日志中收到以下事件资料，具体情况视操作系统而定。

原因
如果在您从电脑登出时 Microsoft Windows 或第三方程式（如印表机驱动程式或病毒扫瞄程式）不停止运行并释放资源，则可能发生此问题。
解决方案
要解决此问题，请使用 Microsoft User Profile Hive Cleanup Service (UPHClean)。UPHClean 在 Windows 卸载用户配置文件时监控电脑并强制关闭打开的资源。因此，电脑可以卸载和协调用户配置文件。
