Deployment Image Servicing and Management (DISM.exe) is a command-line tool that can be used to service a Windows image or to prepare a Windows Preinstallation Environment (Windows PE) image. DISM can be used to service a Windows image (.wim) or a virtual hard disk (.vhd or .vhdx).
DISM replaces the ImageX tool which was deprecated in Windows 8. DISM also replaces Package Manager (Pkgmgr.exe), PEimg, and Intlcfg that were included in previous deployment toolkits. DISM also adds new functionality to improve the experience for offline servicing.
In addition to the command-line tool, DISM is available by using Windows PowerShell. For more information, see Deployment Imaging Servicing Management (DISM) Cmdlets in Windows PowerShell.
DISM can be used to mount and service a Windows image from a .wim file, .vhd file, or a .vhdx file or, in some cases, to update a running operating system. It can be used with older Windows image files (.wim files). However, it cannot be used with Windows images that are more recent than the installed version of the Windows Assessment and Deployment Kit (Windows ADK) in which DISM is distributed. DISM is also installed with the Windows 8.1 and Windows 8 operating system.
