I downloaded a Windows server 2008 Iso yesterday. I thought that the login screen would have that silver background like here: http://engelander.nl/2012/05/14/setting-up-an-windows-server-core-2008-r2-domain-controller-the-sleaszy-way/ But instead it has a bland blue color like here: http://serverfault.com/questions/226772/windows-security-dialog-not-showing-when-logging-on-to-my-server-through-remote How can I change it to the silver one?
