People who create and deploy Windows Vista and Windows 7 images know that .wim is now new native image format used by Microsoft for all its OSs. Microsoft has provided a command line tool called ImageX as part of WAIK short for Windows Automated Installation Kit to work with .wim images. ImageX being a command line tool, sometimes we tend to make mistakes while typing the commands and feel if it had a GUI to work with. Jon Bennett a MCS consultant has felt the same and built an app called GImageX – a GUI for ImageX using C++ and Microsoft’s WIMGAPI API (the wimgapi.dll file from the imagex directory of WAIK)
You can capture, apply, change, mount, delete, export and get info from .wim images using GImageX as you can with ImageX CLI. Below are the screenshots of ImageX CLI and GImageX
