Windows Server 2012 changes all of that. We now can switch between core and full installation, and we can do so on-the-fly. There\u2019s really no more reason why, you should be using a full installation for a server, unless it\u2019s due to an installed application\u2019s or role\u2019s requirements. Unfortunately, there are still a few roles that require the GUI to be installed.<\/p>\n

Convert Full to Core<\/h2>\n
    \n
  1. Log onto the server with an account that has administrative permissions.<\/li>\n
  2. If it isn\u2019t already open, launch the Server Manager console.\"52-figure-01\"<\/a><\/li>\n
  3. From the Server Manager console, click the\u00a0Manage<\/strong>\u00a0menu.<\/li>\n
  4. Click\u00a0Remove Roles and Features<\/strong>.<\/li>\n
  5. \"52-figure-02\"<\/a><\/li>\n
  6. On the Before You Begin screen, click\u00a0Next<\/strong>.<\/li>\n
  7. On the Select Destination Server screen, ensure the server is selected in the server pool, and then click\u00a0Next<\/strong>.<\/li>\n
  8. On the Remove Server Roles screen, click\u00a0Next<\/strong><\/li>\n
  9. On the Remove Features screen, scroll down the list until you see\u00a0User Interfaces and Infrastructure<\/strong>\u00a0and expand it.<\/li>\n
  10. Uncheck\u00a0Graphical Management Tools and Infrastructure<\/strong>\u00a0and\u00a0Server Graphical Shell<\/strong>, and then click\u00a0Next<\/strong>.<\/li>\n
  11. \"52-figure-03\"<\/a><\/li>\n
  12. On the Confirmation screen, review the changes and then click\u00a0Remove<\/strong>.<\/li>\n
  13. When the removal process completes, click\u00a0Close<\/strong>. The server will now need to be rebooted. During the reboot phase, the remaining components will be removed. Do not power off the server.<\/li>\n
  14. After the server reboots, log back in.<\/li>\n
  15. Once you\u2019re logged in, you\u2019ll notice that only a command-prompt window is open. You have successfully removed the graphical interface from Windows Server 2012 R2<\/li>\n
  16. \"52-figure-04\"<\/a>
    \n

    Convert Core to Full<\/h2>\n
      \n
    1. Log onto the server with an account that has administrative privileges.<\/li>\n
    2. Check to see if any graphical user interface components are installed.\n
      Get-WindowsFeature -Name \"Server-Gui-Mgmt-Infra\",\"Server-Gui-Shell\"<\/pre>\n<\/li>\n
    3. The output should look like the following, unless you are running in a minimal install, where only Graphical Management Tools and Infrastructure is installed, giving the admin access to Server Manager in server core.<\/li>\n<\/ol>\n
      \"52-figure-05\"<\/a><\/li>\n
    4. We can that no components are installed, in the figure above. Now we need to install both of the features listed above.\n
      Install-WindowsFeature -Name \"Server-Gui-Mgmt-Infra\",\"Server-Gui-Shell\"<\/pre>\n<\/li>\n
    5. When the features are installed, a warning will be displayed telling you that the server must be restarted. Go ahead and restart the server now.<\/li>\n
    6. When the server completes the reboot process, log in. You should now have a fully functional graphical user interface presented to you.<\/li>\n
