WinPE Optional Components (OC) Reference

Add feature packages, also known as optional components, to Windows PE (WinPE).

Where to get WinPE Optional Components

WinPE optional components are included in the the WinPE add-ons for the Windows Assessment and Deployment kit (ADK).

Optional components are available in Amd64 and Arm64 architectures. The OCs you add to your WinPE image must be from the same ADK build and have the same architecture as your WinPE image. You can find WinPE optional components in the following locations after you install the Windows PE add-ons for the ADK:

  • Amd64 C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\
  • Arm64 C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\arm64\WinPE_OCs\

How to add Optional Components

WinPE OCs are .cab packages that can be added to an offline Windows PE image.

Important

Some optional components have prerequisites that must be installed in order. The table below includes information about prerequisites.

Before adding OCs to a WinPE image, you need a WinPE image (boot.wim). See WinPE: Create bootable media to learn how to make a set of WinPE working files that include a WinPE image. You'll find boot.wim at sources\boot.wim in your working files.

Once you have a WinPE image to work with, you can add packages to it with DISM /add-package. To learn more about using DISM to add packages to a Windows image, see Add or remove packages offline using DISM.

Many WinPE optional components come split into two parts, a language-neutral package, and a set of language-specific packages. When installing an OC that has language-specific packages, you need to first add the language-neutral OC, and then add at least one of its associated language-specific packages. The language-specific and language-neutral resources must be of the same version. You can find OCs in the following folders:

  • Language-neutral - ...\Assessment and Deployment Kit\Windows Preinstallation Environment\<arch>\WinPE_OCs\
  • Language-specific - ...\Assessment and Deployment Kit\Windows Preinstallation Environment\<arch>\WinPE_OCs\xx-xx\

WinPE Optional Components

Area/Optional component name Description
Database/WinPE-MDAC WinPE-MDAC supports Microsoft Open Database Connectivity (ODBC), OLE DB, and Microsoft ActiveX Data Objects (ADO). This set of technologies provides access to various data sources, such as Microsoft SQL Server. For example, this access enables queries to Microsoft SQL Server installations that contain ADO objects. You can build a dynamic answer file from unique system information. Similarly, you can build data-driven client or server applications that integrate information from a variety of data sources, both relational (SQL Server) and non-relational.
File management/WinPE-FMAPI WinPE-FMAPI provides access to the Windows PE File Management API (FMAPI) for discovering and restoring deleted files from unencrypted volumes. The FMAPI also provides the ability to use a password or recovery key file for the discovery and recovery of deleted files from Windows BitLocker Drive Encryption encrypted volumes.
Fonts/WinPE-Fonts-Legacy WinPE-Fonts-Legacy contains 32 font files for various languages/writing scripts. Some of these fonts are no longer used as UI fonts. For example, scripts such as Bangla, Devanagari, Gujarati, Gurmukhi, Kannada, Malayalam, Odia, Tamil, Telugu, and Sinhalese were covered by Mangal, Latha, Vrinda, Gautami, Kalinga, artika, Raavi, Shruti, and Tunga, but in Windows 8, they were all unified under Nirmala UI, a single, pan-Indian font.

Network/WinPE-PPPoE WinPE-PPPoE enables you to use Point-to-Point Protocol over Ethernet (PPPoE) to create, connect, disconnect, and delete PPPoE connections from Windows PE. PPPoE is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. PPPoE enables Windows users to remotely connect their computers to the web. By using PPPoE, users can virtually dial from one computer to another over an Ethernet network, to establish a point-to-point connection between the computers. The computers can use this point-to-point connection to transport data packets.
Network/WinPE-RNDIS WinPE-RNDIS contains Remote Network Driver Interface Specification (Remote NDIS) support. WinPE-RNDIS enables network support for devices that implement the Remote NDIS specification over USB. Remote NDIS defines a bus-independent message set and a description of how this message set operates over various I/O buses. Therefore, hardware vendors do not have to write an NDIS miniport device driver. Because this Remote NDIS interface is standardized, one set of host drivers can support any number of bus-attached networking devices.
Network/WinPE-WDS-Tools WinPE-WDS-Tools includes APIs to enable the Image Capture tool and a multicast scenario that involves a custom Windows Deployment Services client. It must be installed if you intend to run the Windows Deployment Services client on a custom Windows PE image.
Network/WinPE-WiFi-Package WinPE-WiFi-Package is used by Windows Recovery Environment (Windows RE) for built-in recovery functions. This package is included in the base winre.wim file, and not available separately in the Windows PE add-os for the Windows Assessment and Deployment Kit.

Note: Windows PE and Windows RE don't support general wireless networking functions.
Windows PowerShell/WinPE-PlatformID WinPE-PlatformID contains the Windows PowerShell cmdlets to retrieve the Platform Identifier of the physical machine.

Dependencies: Install WinPE-WMI and WinPE-SecureStartup before you install WinPE-PlatformID.

To use the Windows PowerShell cmdlet to retrieve the Platform Identifier, you will need install WinPE-PowerShell package.

Windows PowerShell/WinPE-PowerShell WinPE-PowerShell contains Windows PowerShell–based diagnostics that simplify using Windows Management Instrumentation (WMI) to query the hardware during manufacturing. You can create Windows PowerShell–based deployment and administrative Windows PE–based tools. In addition to deployment, you can use Windows PowerShell for recovery scenarios. Customers can boot in Windows RE and then use Windows PowerShell scripts to resolve issues. Customers are not limited to the toolsets that run in Windows PE. Similarly, you can build scripted offline solutions to recover some computers from no-boot scenarios.

WinPE-PowerShell has the following known limitations:
  • Windows PowerShell remoting is not supported. Any cmdlets that have remoting functionality will return an error.
  • The Windows PowerShell Integrated Scripting Environment (ISE) is not supported.
  • Windows PowerShell 2.0 is not supported.

Windows PowerShell/WinPE-StorageWMI WinPE-StorageWMI contains PowerShell cmdlets for storage management. These cmdlets use the Windows Storage Management API (SMAPI) to manage local storage, such as disk, partition, and volume objects. Or, these cmdlets use the Windows SMAPI together with array storage management by using a storage management provider. WinPE-StorageWMI also contains Internet SCSI (iSCSI) Initiator cmdlets for connecting a host computer or server to virtual disks on external iSCSI-based storage arrays through an Ethernet network adapter or iSCSI Host Bus Adapter (HBA).

Dependencies: Install WinPE-WMI > WinPE-NetFX > WinPE-Scripting > WinPE-PowerShell before you install WinPE-StorageWMI.
Recovery/WinPE-Rejuv WinPE-Rejuv is used by Windows Recovery Environment (Windows RE). This package is included in the base winre.wim file, and not available separately in the Windows PE add-ons for the Windows Assessment and Deployment Kit.
Recovery/WinPE-SRT WinPE-SRT is used by Windows RE. This package is included in the base winre.wim file and not available separately in the Windows PE add-ons for the Windows Assessment and Deployment Kit.
Recovery/WinPE-WinReCfg WinPE-WinReCfg contains the Winrecfg.exe tool, and it enables the following scenarios:

  • Boot from x86-based Windows PE to configure Windows RE settings on an offline x64-based operating system image.
  • Boot from x64-based Windows PE to configure Windows RE settings on an offline x86-based operating system image.
Scripting/WinPE-Scripting WinPE-Scripting contains a multiple-language scripting environment that is ideal for automating system administration tasks, such as batch file processing. Scripts that run in the Windows Script Host (WSH) environment can call WSH objects and other COM-based technologies that support Automation, such as WMI, to manage the Windows subsystems that are central to many system administration tasks.

Dependencies: Install WinPE-Scripting to make sure that full scripting functionality is available when you are using WinPE-NetFX and WinPE-HTA. The installation order is irrelevant.
Scripting/WinPE-WMI WinPE-WMI contains a subset of the Windows Management Instrumentation (WMI) providers that enable minimal system diagnostics. WMI is the infrastructure for management data and operations on Windows-based operating systems. You can write WMI scripts or applications to automate administrative tasks on remote computers. Additionally, WMI supplies management data to other parts of the operating system and products.
Setup/Winpe-LegacySetup Winpe-LegacySetup contains all Setup files from the \Sources folder on the Windows media. Add this optional component when you service Setup or the \Sources folder on the Windows media. You must add this optional component together with the optional component for the Setup feature. To add a new Boot.wim file to the media, add the parent WinPE-Setup, either of the children (WinPE-Setup-Client or WinPE-Setup-Server), and Media optional components. Media Setup is required to support Windows Server 2008 R2 installation.

Add languages to images that include optional components

Tip

To add language packs using Windows PE, you may need to add pagefile support to Windows PE. For more information, see Add pagefile support to your WinPE image.

  1. On a mounted image, list the optional components in the Windows PE image:

    Dism /Get-Packages /Image:"C:\WinPE_amd64\mount"
    
  2. Review the resulting list of packages, and add the corresponding language packs for each package in the image, including the base Windows PE language pack.

    Dism /Add-Package /Image:"C:\WinPE_amd64\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\fr-fr\lp.cab"
    
    Dism /Add-Package /Image:"C:\WinPE_amd64\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\fr-fr\WinPE-HTA_fr-fr.cab"
    

    where …WinPE_OCs\fr-fr\lp.cab represents the base Windows PE language pack.

  3. If you're adding language packs for a language that requires additional font packages, add the font packages for these languages. Here's an example for Japan:

    Dism /Add-Package /Image:"C:\WinPE_amd64\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\WinPE-Font Support-JA-JP.cab"
    
  4. Verify that the language packs are part of the image:

    Dism /Get-Packages /Image:"C:\WinPE_amd64\mount"
    

    Review the resulting list of packages and verify that the for each optional component, including the base Windows PE image, that there is an associated language pack.

  5. Change the regional settings to the language you'd like to use:

    Dism /Set-AllIntl:en-US /Image:"C:\WinPE_amd64\mount"
    

    To switch languages while in Windows PE, use wpeutil setmuilanguage. See Wpeutil command-line options for more information.
