The Deployment Image Servicing and Management Tool User Interface (DISMUI) allows you to modify your Windows Embedded Standard 7 image by using an easy to use graphical user interface. By using DISMUI you can add and/or remove Feature Packages at any time by just selecting the packages. The software will take care of the rest. A dependency check ensures that all needed Feature Packages are selected.

With DISMUI there is no need to use the DISM.exe command line anymore!

DISMUI has been updated to work with the RTM version of Windows Embedded Standard 7.

A problem has been fixed which prevented DISMUI to work on other languages than English.
