Windows Server 2016

By default, when logging in to Windows Server 2016, Server Manager automatically starts with your session. I find it really annoying. Here are three ways to disable automatic startup of Server Manager:

Method One: Disable Server Manager using server manager properties.

1. Within Server Manager click on manage and then “Server Management Properties”:
   
2. Within Server Manager Properties, tick the box that says “Do not start Server Manager automatically at logon”:
   

Method Two: Use Group Policy Editor

1. Run gpedit.msc to edit the policy of the local machine or domain wide Group Policy Management Console
2. Go to Computer Configuration -> Administrative Templates -> System -> Server Manager:
   

Method Three: Disable Server Manager from Task Scheduler

1. Open Task Scheduler
2. In the left hand navigation pane,  go to Task Scheduler Library -> Microsoft -> Windows -> Server Manager
3. Right Click on the “ServerManager” Task and choose disable:
   

Method Four: Use PowerShell to disable the Server Manager Scheduled Task

1. Run Windows PowerShell
2. Enter the command:

Get-ScheduledTask -TaskName ServerManager | Disable-ScheduledTask -Verbose

You should see output like this:

 

So many methods to achieve the same result. Depending on how many servers you are looking after will determine which is the best option for you. I hope this helps.
