Add-WindowsFeature

The Add-WindowsFeature cmdlet allows you to install specified roles, role
services, and features on a computer that is running Windows Server 2008
R2.

Add-WindowsFeature [-Name] <string[]> [-IncludeAllSubFeature] [-logPath <string>] [-WhatIf] [-Restart] [-Concurrent] [<CommonParameters>]

The Add-WindowsFeature cmdlet allows you to install specified roles, role
services, and features on a computer that is running Windows Server 2008
R2. The Add-WindowsFeature cmdlet functions similarly to the Add Roles
Wizard and Add Features Wizard that you can start from the Server Manager
UI. As in those wizards, you can add more than one role, role service, or
feature per session, and all roles, role services, or features that are
required by those Windows features you want to install are added
automatically.

You can find a list of command IDs for all roles, role services, and
features in the topic "Overview of Server Manager Commands" in the Server
Manager Help.

-Name

Specifies the command IDs of roles, role services, or features you
want to install by using the Add-WindowsFeature cmdlet. Alternatively,
an array of Feature objects will also be accepted.

You can find a list of command IDs for all roles, role services, and
features in the topic "Overview of Server Manager Commands" in the
Server Manager Help.

-Concurrent

Allows concurrent instances of the Server Manager Add-WindowsFeature
or Remove-WindowsFeature cmdlets to be running at the same time.
Do not add this parameter unless you are installing roles, role
services, or features that are downloaded separately from Windows
Server 2008 R2, and you want to install Windows features on which
the downloaded technology depends at the same time.

The use of this switch is not recommended. This switch is intended
for out-of-band feature(s) to install their dependencies.
