Windows Deployment Platform Components - Deployment Image Servicing and Management

Deployment Image Servicing and Management (DISM) is a new command-line tool that you can use to service Windows 7 images offline before deployment. With DISM, you can install, remove, configure, and update Windows features, packages, device drivers, and international settings. You can use some DISM commands to service online Windows 7 images.

You can use DISM to:
• Add, remove, and enumerate packages.
• Add, remove, and enumerate drivers.
• Enable or disable Windows features.
• Apply changes based on the offlineServicing section of an Unattend.xml answer file.
• Configure international settings.
• Upgrade a Windows image to a different edition.
• Prepare a Windows PE image.
• Take advantage of better logging.
• Service earlier versions of Windows.
• Service all platforms (32-bit, 64-bit, and Itanium).
• Service a 32-bit image from a 64-bit host, and vice versa.
• Use old Package Manager scripts.

DISM consolidates the functionality of the Package Manager (Pkgmgr.exe), PEImg, and Intlcfg tools from Windows Vista. It provides one tool to use for servicing Windows 7 and Windows PE images.
