@Jan~ I have a few suggestions regarding ISO downloader software.
1. In the program itself, please add an update section. Unless I am missing it I don't see anything to check for a newer version.
2. Please add a description below the product that briefly describes the product. After you choose Edition then Language, please add a description such as Windows Preinstallation Environment is..
3. If I didn't request this already, please add any MSDaRT versions and add a separate category for it.
4. Please add a BACK button to the screen so the user can go back to the previous screen.
5. Please add a note to Window Editions stating a user must be log in before downloading the ISO.
