A shorter swapper in C:

#include 

int main()  
{
    if (SwapMouseButton(TRUE))
        SwapMouseButton(FALSE);

    return 0;  
}

Install Windows SDK and Compile in x86_x64 Cross Tools Command Prompt via eg. cl swapmbtn.c "C:\Program Files (x86)\Windows Kits\10\Lib\10.0.15063.0\um\x64\user32.lib"

Rename main to WinMain to prevent the console window flash.
