This one is pretty minor and came up in the forums at SQL Server Central. You may have noticed that the Registered Servers window is tabbed with the Object Explorer window. In SQL Server 2005, they were in the same window, stacked on top of each other. To get back to the “good old days” configuration, you can right click on the Registered Servers tab and select Floating. This will cause the window to detach and appear somewhere on your screen. Right click on it again and select Dockable. Now drag it on to the Object Explorer window and it should settle in on top. Ta da, back with the old GUI.
