HOW DO I INSTALL GUI??

Hello

Hi JACOB,

Yes, you can add the GUI realted feature via powershell, please run the powershell cmdlets below as Sneff posted:

Get-WindowsFeature Server-Gui-Mgmt-Infra, Server-Gui-Shell | Install-WindowsFeature restart

And this article is for your reference, which list the differences between server core and full install:

Do you need Internet to peform this command as this computer does not have any internet acess

Hi JACOB,

If the server can't connect internet, you will need to use Windows Server 2012 R2 installation media and source parameter:

1.Insert the updated Windows Server 2012 R2 DVD into the computer's DVD drive.

2.Type the following command to determine the index number that's required for steps 3.

3.Type the following PowerShell command, in which <drive> represents the location of the Windows Server 2012 R2 installation files and <index> represents the numbered index from step 2:

Install-WindowsFeature Server-Gui-Mgmt-Infra,Server-Gui-Shell Source wim:<drive>:\sources\install.wim:<index>
For example: If your media is on drive F, and you are installing the full version of Datacenter, enter the following command:
Install-WindowsFeature Server-Gui-Mgmt-Infra,Server-Gui-Shell Source wim:f:\sources\install.wim:4
