The Silentlaunch has been updated to v2, please download it here
* Enviroment variables, like %systemroot%, %programfiles%
* Configfile is based on %homedrive% and not hardcoded to C:\
* Recompiled using Visual Studio 2010, c++, win32. Source code available!
SilentLaunch could be used to replace a shell and usally a HTPC box with XBMC, Boxee or similar can take advantage of this!
If you need help setting it up, just post a comment!
