How to disable auto launch of server manager

On the windows server machines, I am taking 2012 as an example, server manager launches automatically once we login to the machine.

To disable that we need to set below option.

1. Open the “Server Manager”.
2. Select “Manage” on the top bar.
3. Select “Server Manager Properties” from the drop down menu.
   
4. Select the option “Do not start Server Manager automatically at logon”.

This can also be set using the below registry.

[HKEY_CURRENT_USER\Software\Microsoft\ServerManager]
“DoNotOpenServerManagerAtLogon”=dword:00000001

And the reverse option is

[HKEY_CURRENT_USER\Software\Microsoft\ServerManager]
“DoNotOpenServerManagerAtLogon”=dword:00000000

You can set the same key in HKLM to set it for all users.But we should not keep this registry value “DoNotOpenServerManagerAtLogon” in HKCU at that time as the User key will be given preference.
