If there is no other admin accounts in the system, it is very difficult to switch account back. This is because we can't "sudo" anymore. The only way to fix it is entering single user mode and editing /etc/group. I think there should be some warning at least if the user is the only administrator in the system and he tries to become "Standard" user (by accident in my case).
