Windows Automated Installation Kit (WAIK) is a software utility from Microsoft that helps system administrators to install, customize, manage and deploy the Microsoft Windows and Windows Server family of operating systems.

Windows AIK contains a set of handy tools and documentation which support the configuration and deployment of Windows operating system. Users can automate Windows installations, capture Windows images with ImageX, configure and modify images using Deployment Imaging Servicing and Management (DISM), create Windows PE (Preinstallation Environment images, and migrate user profiles and data with the User State Migration Tool (USMT) via this powerful Windows AIK.

The major change for Windows Automated Installation Kit for Windows 7 SP1 is that it includes Windows PE (WinPE) 3.1, which is being released as an WAIK supplement for Windows 7 SP1. Win PE 3.1 includes all optional components and language packs, which can be applied to customize the boot.wim and winre.wim images that are part of the Windows 7 SP1 installation media.

You can continue to use the Windows 7 RTM version of the Windows AIK to install both Windows 7 and Windows 7 with Service Pack 1.

Microsoft will not re-release the Windows AIK will not be re-released to support Windows 7 with Service Pack 1. Thus, you have to have Windows Automated Installation Kit (Windows AIK) for Windows 7 RTM with WinPE 3.0 before using the Windows PE 3.1 supplement. The WinPE 3.1 supplement is optional. If you do not need to modify the SP1 boot.wim and winre.wim files, you can continue to use the Windows AIM for Windows 7 RTM without installing the supplement.

  • The number in the Version registry value is 3.1 to reflect the new Windows PE version.
  • The Windows PE 3.1 base image contains Remote Network Driver Interface Specification (RNDIS) binaries. These binaries are also available for Windows PE 3.0 as a hotfix. For more information, see Knowledge Base Article ID: 979265.

  • Windows PE 3.1 includes bug fixes that are related to the Windows PE version that is included with Windows 7 SP1.
