When I try to restart or shutdown windows, the system seems to hang. Task manager wont display, no programs will open ( I get a warning which says the program can not open because windows is shutting down...) I end up having to restart manualy. The Event viewer displays this message: "Windows saved user **EDITED**\HP_Administrator registry while an application or service was still using the registry during log off. The memory used by the user's registry has not been freed. The registry will be unloaded when it is no longer in use. This is often caused by services running as a user account, try configuring the services to run in either the LocalService or NetworkService account." I've tried uninstalling adware remover, antivirus software, other software and still no luck. How can I figure out what service is hanging?
