How to tell the OS to use the environment provided by the WinForm application instead from system environment.

Example : My WinForm application uses C++ runtime dll's(msvcm80.dll, msvcp80.dll and msvcr80.dll) and bundling them as part of the application. How to make sure that my application will use the C++ runtime dll's that bundled along with product even though the dll's present else where in the system(c:\Windows\Winsxs).
