These libraries are the C runtime, C++ runtime and ATL runtime. You can't turn off the first two since then are essential to starting your program running. You can however link to them statically so you won't need to carry them around as DLLs. To do that you go to your project settings C/C++,Code Generation,Runtime Library and choose "Multi threaded" or "Multi threaded Debug" instead of "Multi threaded DLL" or "multi threaded debug dll". Make sure to do that in all the settings configurations (Debug, Relaese etc')
As for the 3rd library (ATL100.dll), it might be affected by this settings as well, I'm not sure. you can potentially remove if you stop using the function imported from it. The dependency walker can tell you what functions you're using from that library. If you can;t stop using that function, its possible that library also has a static version (.lib file instead of .dll file)
