Description

The Install-WindowsFeature cmdlet installs the specified features on a computer that is running Windows Server, or on an offline virtual hard disk (VHD) on which Windows Server is installed. This cmdlet works similarly to the installation of roles and features in Server Manager, with an important exception: the cmdlet does not install management tools for the features by default. To install management tools such as snap-ins on a target server, you must add the IncludeManagementTools parameter to your command.

This cmdlet requires elevation; you must be running a Windows PowerShell session as an administrator to use this cmdlet.

Examples

Example 1

Install-WindowsFeature -Name Web-Server -IncludeAllSubFeature -ComputerName Server1 -WhatIf

This example shows what is installed with Web Server (IIS), including all role services, on a computer named Server1. By adding the WhatIf parameter, you can view the results of the installation command without running it.

Example 2

Install-WindowsFeature -Name Web-Server -IncludeAllSubFeature -IncludeManagementTools -ComputerName Server1 -Credential contoso.com\johnj99

This example installs Web Server (IIS), including all role services and applicable management tools, on a computer named Server1, by using the credentials of a user account named contoso.com\johnj99.

Example 3

Install-WindowsFeature -ConfigurationFilePath d:\ConfigurationFiles\ADCSConfigFile.xml

This example installs all roles, role services and features that are specified in a configuration file named ADCSConfigFile.xml. The configuration file was created by clicking Export configuration settings on the Confirm installation selections page of the Add Roles and Features Wizard in Server Manager.

Example 4

$servers = ('server1', 'server2')
foreach ($server in $servers) {Install-WindowsFeature -ConfigurationFilePath D:\ConfigurationFiles\ADCSConfigFile.xml -ComputerName $server}

This example installs Active Directory Certificate Services (AD CS) as specified in a configuration file named ADCSConfigFile.xml. AD CS is installed on a list of computers that is contained in the variable $servers. The configuration file was created by clicking Export configuration settings on the Confirm installation selections page of the Add Roles and Feature Wizard in Server Manager. On the first line, the value of the $servers variable is set; on the second line, the installation instructions in the ADCSConfigFile.xml configuration file are applied to each of the servers that has been named in $servers.

Example 5

Get-WindowsFeature -Name Web-* | Install-WindowsFeature

This example retrieves a list of all Windows features beginning with the characters Web, and then pipes the resulting list to Install-WindowsFeature. The result of this cmdlet is all features that start with Web are installed on the local computer.

Example 6

Install-WindowsFeature -Name Web-Server -Source \\server2\winsxs

This example installs Web Server (IIS) on the local computer, specifying that the source of feature files for the installation is a folder, winsxs, on a computer named Server2. The computer account of the local computer must have Read permissions on the specified share.

Parameters

-ComputerName

Installs one or more available features on a specified remote computer. This parameter accepts only one computer name. If this parameter is not added, or no computer name is specified, the default target is the local computer.

Valid values for the parameter include a NetBIOS name, an IP address, or a fully qualified domain name of a remote computer that is running Windows Server

To use an IP address of a remote computer as the value of this parameter, your command must include the Credential parameter. The computer must either be configured for HTTPS transport, or the IP address of the remote computer must be included in the WinRM TrustedHosts list on the local computer. For information about adding a computer name to the WinRM TrustedHosts list, see "How to Add a Computer to the Trusted Host List" in about_Remote_Troubleshooting.

Type:String
Aliases:Cn
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ConfigurationFilePath

Provides a single path to a configuration file which specifies roles and features to be installed and any configuration parameters needed. The path can be specified by using a local relative path (such as D:\myfolder) or by using built-in environment variables prefixed with the $env tag (such as $env:systemdrive\filename). A configuration file can be generated by running the Add Roles and Feature Wizard in Server Manager.

If this parameter is specified, then the Name parameter cannot be used.

Type:String
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Credential

Specifies a user account that has access rights to perform this action. If the parameter is not added, or no value is specified, the default value of this parameter is the current user. Enter a user name in one of the following formats. Quotation marks are optional.

"UserName"

"Domain\User"

"[email protected]"

A Credential object returned by the Get-Credential cmdlet.

If a user name is entered, then a prompt for a password is displayed.

Type:PSCredential
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-IncludeAllSubFeature

Specifies that all subordinate role services and all subfeatures of parent roles, role services, or features specified by the Name parameter should be installed.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-IncludeManagementTools

Specifies that all applicable management tools of the roles, role services, or features specified by the Name parameter should be installed.

Note: Although management tools are installed by default when you are installing features by using the Add Roles and Feature Wizard, management tools are not installed by default when you install features by using the Install-WindowsFeature cmdlet; this parameter must be added to install management tools.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-LogPath

Specifies a name and path to a log file. Add this parameter if the results of your command must be stored in a log.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Name

Specifies a list of features to install. This parameter does not support wildcard characters. If this parameter is specified, then the ConfigurationFilePath parameter cannot be used.

Type:Feature[]
Position:0
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Restart

Specifies that the target computer is restarted automatically if a restart is required by the installation process for the specified roles or features. This parameter cannot be used with the Vhd parameter.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Source

Specifies the path to feature files if the files are not available in the local feature store of the target computer or VHD. Valid values for this parameter are either a network path or the path to a Windows image file (WIM). If you are installing roles or features on an offline VHD, you must use a mounted WIM. It is not necessary to mount the WIM file for installing on a running physical computer, because a WIM is mounted internally for deployments to a physical computer. Specify the path by using a local relative path, or by using built-in environment variables that are prefixed with the $env tag as shown in the following examples.

If this parameter is used in combination with the -ComputerName parameter, the source path must be accessible by the target computer (e.g. local devices/drives/paths on the client system will cause the installation to fail).

The path specified in this parameter is only used if the command cannot find feature files in the local side-by-side store of the specified target computer or VHD. The command searches for feature files in the following order:

  1. On the target computer or offline VHD.

  2. Path specified as the value of this parameter. If you add a UNC path, verify that the computer account of the target server has Read permissions on the share. The computer account should be in one of the following formats: DOMAIN\SERVERNAME$ or SERVER$

  3. Repository path specified by the Group Policy Object (GPO). Specify settings for optional component installation and component repair located in Computer Configuration/Administrative Templates/System in Local Group Policy Editor. This Group Policy setting controls the following Windows Registry setting: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Servicing\LocalSourcePath.

  4. Windows Update.

This parameter is optional.

Type:String[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Vhd

Specifies the path to an offline VHD. The path can either point to a VHD file or to a location on which the VHD is already mounted by using Deployment Image Servicing and Management (DISM) tools.

The VHD can be on a local disk on the target computer or on a network shared folder. If the VHD is in a network shared folder, then the value of this parameter is a UNC path to the VHD. In this case, the computer account of the computer that you are using to mount the VHD must have read and write permissions (Read/Write permissions in the File Sharing dialog box or Full Control on the Security tab of the folder Properties dialog box) on the shared folder or the VHD will not be accessible. Local loopback UNC paths are not supported. Use either of the following formats for the computer account: DOMAIN\SERVERNAME$ or SERVERNAME$.

Add the ComputerName parameter to specify the target computer you want to use to mount the VHD. If the ComputerName parameter is not specified, then the local computer is used. The computer that you are using to mount the VHD must be running Windows Server. Any local path, such as D:\myFolder. that is specified by using this parameter is always relative to the target computer.

Type:String
