The Windows ADK now includes Windows Imaging and Configuration Designer, the Windows Assessment Toolkit, the Windows Performance Toolkit, and several new and improved deployment tools that can help you automate a large-scale deployment of Windows 10.

Windows Imaging and Configuration Designer (ICD)

  • Quickly create a provisioning package that you can use to customize devices without re-imaging.
  • Build a customized Windows 10 image for specific market segments and regions.

See Getting started with Windows ICD for more information.

Push-button reset incorporates system updates by default

Users can now refresh or restore their PCs to the updated version of the system files, instead of having to reinstall each update individually.

Partial language packs now available

Want to add more languages for users when they turn on their device? Instead of adding full language packs, save space by adding just the base user interface files for a language. Later, if your user needs handwriting or voice recognition capabilities, Windows can download them as needed.

For more information, see Language Packs (lp.cab).

New package type: Capabilities

This new Windows package type lets you request services like Microsoft .NET or languages without specifying the version. Use the DISM tool to search multiple sources like Windows Update or your corporate servers to find and install the latest version.

Save space by running Windows from compressed OS files

You can now run Windows directly from compressed files. This is similar to WIMBoot, introduced in Windows 8.1 Update 1. This new process uses individual files instead of a static WIM file. When updating system files, Windows now replaces the old files instead of keeping both copies.
