How to reinstall Server Manager and disable Server Manager at startup for all users and login user

Server-Manager

Server Manager is a management console in Windows Server that helps IT professionals provision and manage both local and remote Windows-based servers from their desktops. Server Manager is installed by default with all editions of Windows Server and can be used to manage server core options. The Server Manager was first introduced with Windows Server 2008 and it gave administrators the ability to install, configure and manage server roles and features and since then, it has become the central control point for the administration of Windows Server.

You might have intentionally or unintentionally uninstalled .NET Framework from your server, thus resulting in broken Server Manager. This might also result in PowerShell not launching correctly on your device. This error is also common when you performed an in-place upgrade of Server 2019 (Desktop Experience). The following executables will be missing "ServerManager.exe & ServerManagerLauncher.exe".

To reinstall .NET Framework, please follow the steps in this guide. "How to enable or disable DotNet Framework (NetFx3) via PowerShell, Control Panel, and DISM in Windows". In this case, I will recommend using the CLI described in step 1.

Part 1 – Reinstall Server Manager: You will have to launch PowerShell as an Administrator as shown below.

Then run the following DISM command below to have Server Manager re-installed on your system. For more information on DISM, please see the following posts: Remove Windows 10 Apps with DISM:How to remove pre-provisioned apps from Windows Image, how to resolve DISM unspecified error when removing preinstalled packages, and how to add languages to Windows image using DISM and PowerShell.

As you can see below, the server manager is now re-installed and can be used to install, configure and manage server roles and features.

You may create a new Policy, since I have an existing Domain Policy, I will modify this by editing it as shown below.

Expand the Computer Configuration\Administrative Templates\System\Server Manager and on the right side of the window, select “Don’t display Server Manager automatically at Logon” and
– Select Enable and click on OK.

As you can see, the policy has been enabled.

Note: If you created a new policy, you will have to link the Group Policy in the right OU with the Servers that you want to Apply or use the Security Filtering to Filter the Servers that you want to apply.See the hyperlink for the difference between GPUpdate and GPUpdate /force, and for some group policy implementations, see the following link.
