Hi, WinBuilder is unique because it was created since the beginning with the purpose of creating custom Windows platforms, not just Windows PE. It provides a script syntax similar to batch and INI syntax along with a complete GUI support and a structure for running scripts in a given order/categories. It allows creating scripts that include files inside the code, in the same manner as people exchange email messages with attachments everyday. Do you need to learn a new scripting language? Yep. This is not difficult since most times you can use one line per command like: RegImport,c:\myFile.reg http://code.google.com/p/winbuilder/wiki/regimport It is not possible to please everyone as you might have noted. The core of each WinBuilder project can be changed by anyone and wb itself has been developed since years with the support and feedback from different people all around the world. This is what I do, I love creating boot disks and I am a programmer that works closely with those who share similar tastes. In case anyone has requests for features not already provided by WinBuilder to create a WinPE Builder, I will be glad to work on them.
