Disable Server Manager from Loading at Startup in Windows 2008 Server
If you are running a Windows 2008 Server at your workplace or even at home I'm sure you have noticed that the Server Manager console starts up every time you boot your server. Unlike the Initial Configuration Tasks window that also pops up, there isn't a Don't show this window at login box to check.
There are a couple of ways you can prevent this window from opening when you boot your Windows 2008 server in case you don't want to have it open on each startup. One way is a registry edit and the other is a simple checking of a checkbox.
For the registry edit open the Windows registry editor by clicking on Start and typing in regedit in the search box.
For Windows Server 2008 SP2 browse to the following key.
