Deployment Image Servicing and Management
The Deployment Image Servicing and Management (DISM) tool in Windows 7 provides a central place for
you to build and service Windows images ofine. DISM is a scriptable command-line tool that combines
the functionality of several ofine image management utilities provided with Windows Vista, including
International Settings Conguration (Intlcfg.exe), PEImg, and Package Manager (PkgMgr.exe).
Dynamic Driver Provisioning
With Dynamic Driver Provisioning in Windows 7, you can reduce the size of system images and the
number of images to manage. Plus, you won’t need to update images when new hardware is introduced.
Drivers are stored centrally—separate from images—and can either be installed dynamically based on
the Plug and Play IDs of a PC’s hardware or as predetermined sets based on information contained in the
basic input/output system (BIOS). When clients are deployed, Plug and Play enumeration is performed,
and applicable drivers from the deployment server are located and applied. Reducing the number of
drivers on individual computers reduces the number of potential driver conicts, ultimately speeding up
installation and setup times.
Multicast Multiple Stream Transfer
With Multicast Multiple Stream Transfer in Windows 7, you can deploy images across networks more
efciently. Instead of requiring separate direct connections between deployment servers and each client,
Multicast Multiple Stream Transfer enables deployment servers to broadcast image data to multiple
clients simultaneously. Multicast Multiple Stream Transfer also helps servers group clients with similar
bandwidth capabilities into network streams, ensuring the fastest possible overall transfer rate. You can
dene minimum performance thresholds to automatically remove slower PCs from a multicast group.
(This is different from the standard multicast introduced in Windows Server 2008, in which the slowest PC
throttles the transfer rate for all clients.)
Windows 7 for IT Pros:
Reduce Costs by Streamlining PC Management
Easier Deployment
Easier Deployment
Windows 7 enhances desktop and application deployment in several ways, beginning with improvements
in application and hardware compatibility that reduce the evaluation and readiness cycle. New system
imaging tools expand on the advances made in Windows Vista, helping you manage operating system
images by using a single, consolidated toolset. Multicast Multiple Stream Transfer improves system image
delivery over the network, and Dynamic Driver Provisioning helps reduce image sizes. Through our
improved migration tools and enhancements to VHD image management and deployment, rolling out
Windows 7 is faster and easier than ever.
Note: For a detailed discussion of enhancements that support application and device compatibility, please see the “What’s New in
Windows 7” section.
