I've a Windows 7 installation with 2 users, one administrator and the other is not. If I try to logon with the standard user it show the Welcome Screen and them logoff immediately. If I logon with the administrator user or if I set the standard used as an administrator it works without problems.

Any idea?

Windows 7 Ultimate running on a netbook, AVG Antivirus, no special software or any other specific configuration.
