Since some of my test machines are a touch low on resources, having to wait for the server manager process to finish loading can be a little bit painful.

There are group policy and local policy options to suppress this in addition to editing the registry.

There is always the option to disable it directly from Server Manager, but I’d rather automate this.  For completeness sake, the below shows how to manually disable Server Manager on a Windows Server 2012 R2 server. 

Select “Manage” in the top right hand corner, then Server Manager properties

In the Server Manager Properties Window, you can choose to disable it from starting up automatically at logon. 

Group Policy

The option to control via a GPO is contained here:

Computer Configuration\Administrative Templates\System\Server Manager

Using the Group Policy Management Console on Windows 2012 R2, we can set the policy as follows:

When the GPO is refreshed on the machines that fall under the scope of the policy, the settings will be applied.  This then greys out the “Do not start Server Manager automatically” at logon option.

Controlling Via Registry

In addition we can also set a registry key automatically via a script to set the required registry key.

HKCU\Software\Microsoft\ServerManager\DoNotOpenServerManagerAtLogon

REG_DWORD  0x1

Working With Cmd Prompt

To query this via cmd prompt:

REG.exe  Query HKCU\Software\Microsoft\ServerManager /V DoNotOpenServerManagerAtLogon

To set this via cmd prompt:

REG.exe Add HKCU\Software\Microsoft\ServerManager /V DoNotOpenServerManagerAtLogon /t REG_DWORD /D 0x1 /F

(Note that the above is one line that may wrap)

Working With PowerShell

We can retrieve the current configuration using the first two commands, whilst the third one sets the value: 

Get-Item HKCU:\Software\Microsoft\ServerManager

 

Get-ItemProperty -Path HKCU:\Software\Microsoft\ServerManager -Name DoNotOpenServerManagerAtLogon | select DoNot OpenServerManagerAtLogon | Ft –AutoSize

 

New-ItemProperty -Path HKCU:\Software\Microsoft\ServerManager -Name DoNotOpenServerManagerAtLogon -PropertyType DWORD -Value "0x1" –Force

(Note that the above are all one line that may wrap)

Cheers,
