You are exaggerating a great deal. It is a single function call, ExpandEnvironmentStrings, documented at http://msdn.microsoft.com/en-us/library/ms724265%28v=vs.85%29.aspx. Patching cmdproxy.c to use ExpandEnvironmentStrings before calling CreateProcess would add at most 10 lines of code. This is by no means "reimplementing half of cmd.exe."
