I successfully built a Win7 PE build however am running into a couple walls.
First of all the default build uses the BSD Devil mouse cursor for the busy cursor and I would like to change this since it will not fly in my environment (Personlly I don't care). I have looked all over the web and cannot find any information on how to change the cursors.
Second when I try to place an icon on the desktop it does not seem to work using standard winbuilder commands. The MMC addon seems to place it's shortcut fine, and when I use the same method nothing happens.
The devil mouse: as far as I know, it is only used in Joshua's Win7RecuePE. So, if you use that as base, you have to live with it. But you can use every other Win7PE project as base for your development.
The "Add_Shortcut" is NOT standard WinBuilder command. It is a command using the "Common_API". The "Common_API" is developed to make it easy to add apps to different PEs.
To use the common API successfully for shortcuts, inside your script (e.g. for Ghost) you must define:
%ProgramTitle%=Ghost (or something other valid)
%ProgramEXE%=Ghost.exe (or something other valid)
%ProgramFolder%=Ghost (or something other valid)
