noteNote
This topic includes sample Windows PowerShell cmdlets that you can use to automate some of the procedures described. For more information, see Using Cmdlets.

To discover the server roles and features on your computer, run the Windows PowerShell cmdlet Get-WindowsFeature.

To install a server role or feature, make a note of the role or feature name in the output from Get-WindowsFeature and then run Install-WindowsFeature <featurename>.

You can install (or uninstall) more than one feature at a time by separating feature names with commas. For example, to install both Server Graphical Shell and Windows PowerShell ISE (and its dependencies), if you run Install-WindowsFeature Server-Gui-Shell,PowerShell-ISE, the server is converted to Server with a GUI mode.

Appending the –WhatIf parameter to either Install-WindowsFeature <featurename> or Uninstall-WindowsFeature <featurename> displays any dependent features that will be installed or uninstalled along with the feature you have specified.

To uninstall a server role or feature, run the Windows PowerShell cmdlet Uninstall-WindowsFeature <featurename>

noteNote
When you uninstall a role or feature with this command, the binary files for it remain on the disk. This allows you to add the role or feature later without having to access an installation source (such as an installation DVD or WIM image). To completely remove the files for the role or feature from the disk or to reinstall a role or feature that has been completely removed, see “Working with Features on Demand” in this topic.

In previous versions of Windows, even if a server role or feature was disabled, the binary files for it were still present on the disk, consuming space. In Windows Server 2012, not only can you disable a role or feature, but you can also completely remove its files, a state shown as “removed” in Server Manager or “disabled with payload removed” in Dism.exe. To reinstall a role or feature that has been completely removed, you must have access to an installation source.

To completely remove a role or feature, use –Remove with the Uninstall-WindowsFeature cmdlet of Windows PowerShell. For example, to completely remove Windows Explorer, Internet Explorer, and dependent components, run the following Windows PowerShell command:

Uninstall-WindowsFeature Server-Gui-Shell -remove

To install a role or feature that has been completely removed, use the Windows PowerShell –Source option of the Install-WindowsFeature Server Manager cmdlet. The –Source option specifies a path to a WIM image and the index number of the image. If you do not specify a –Source option, Windows will use Windows Update by default.

To install a removed role or feature using a WIM image, use these steps and Windows PowerShell cmdlets:

  1. Run Get-windowsimage –imagepath <path to wim>\install.wim, and make note of the index of the image for the Server with a GUI version of Windows Server 2012.

  2. Install-WindowsFeature <featurename> -Source wim:<path>:<index>, where:

    Featurename is the name of the role or feature from Get-WindowsFeature

    Path is the path to the WIM mount point

    Index is the index of the server image from Step 1.

For example, if the Server with a GUI image is in D:\sources: Install-WindowsFeature <featurename> -Source wim:d:\sources\install.wim:4

You can also specify a source for servers that are domain members using Group Policy. Navigate to Computer Configuration > Administrative Templates > System > “Specify settings for optional component installation and component repair”

noteNote
Permissions might affect the system’s ability to access Windows features for installation over a network. The Trusted Installer process runs within the machine account. If you encounter network access issues, try issuing a net use command (for example, net use * \\path\to\network) to connect to the network source and then copy the source locally. Then use the local copy as the installation source.
