Managing your images is easier than ever with DISM! Whether your images are stored in the .wim or .vhd format DISM is the tool you'll want to use when it comes time to make changes to your images. DISM allows you to add, remove and enumerate packages and drivers, enable or disable Windows features, configure international settings, upgrade a Windows image to a different edition, provide better logging capabilities, service all platforms 32-bit, and 64-bit. If you have ever struggled with Package Manager (pkgmgr), Windows Preinstallation Environment (PE) command-line tool PEimg or Intlcfg--DISM replaces them all. Plus, DISM is great for helping to document exactly what is in an image so you won't have to!
