Hi, I saw a new function that is called Driver Update in Winodws 7, http://www.intowindows.com/how-to-update-vistawindows-7-drivers-instantly/ Is there any API supported for this? Can I implement this function throw C# or C++?

The Setupapi.dll includes all functions to install drivers. Check http://pinvoke.net/ for an C# wrapper of all functions. If you have question, ask in the MSDN forums: http://social.msdn.microsoft.com/Forums/en-us/categories André"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/
