Hi I was wondering if anybody can help me please?...... I wish to modify my Windows 7 installation media so that it installs a default logon background image and a default background (desktop) image of my choosing. I have a clean ISO image of Windows 7 SP1 to work with. I am happy to simply replace the two .jpg images in question with those I wish to use as my defaults but I do not know where they are stored. I have used WAIK and ImageX and managed to mount install.wim Unfortunately I still don't know where to begin. I have already added an autounattend.xml file to the root of my installation media which injects the product key and this works ok. Can I add some lines to this xml file to reference different jpg's which I can add to the installation media? What is OOBE.xml and the OOBE folder? I have read about this but don't understand whether I can use this method and how it should be done. Please help. Many thanks indeed.
