A. DISM is a new tool introduced with Windows 7 and Windows Server 2008 R2. It unifies functionality previously available in multiple other commands such as pkgmgr, PEimg and Intlcfg. DISM is included with Windows 7, Windows 2008 R2 and the Windows Automated Installation Kit (WAIK). While DISM also incorporates ImageX functionality that's used for WIM mounting and manipulation, ImageX is not being replaced by DISM and is still used for image capture and deployment.

DISM can be used for:

  • Enumerating and modifying packages and drivers

  • Enabling/disabling Windows roles and features

  • Configuring international settings

  • Upgrading a Windows image

  • Servicing versions of Windows online

  • Applying offline servicing components of Unattend.xml file

See the following for an example of viewing then mounting a WIM file with DISM. The bold text inidcates commands that I entered.
