Microsoft Windows 7 and Windows Server 2008 R2 or higher automatically take care of user profiles that fail to unload. The logoff process continues as normal after the disconnect, but users experience a faster logoff.
This behavior is usually caused by improper coding in either Microsoft software or third-party software. Close the Local Group Policy Editor, run the following command in Command Prompt window to update the group policy just to be sure the change takes affect right away.
This behavior can occur if applications do not close their registry handles when they are terminated. With Instant LogOff, you can manage user profiles that fail to unload during logoff. When we click user icon it shows log in and immediately it lof off autometicly. At Administration > Performance you find Instant LogOff.
