Editing a .Wim file is very simple. \nFirst create a folder that will be used as a mount point.  I'm going to use c:mountwim\nDownload imagex and run this command imagex /mountrw c:wimImagesimage.wim 1 c:mountwim\nWhen you are finished you must commit your changes or they will all be lost.  That can be done by using this command.\nimagex /unmount /commit c:mountwim
