( Note: I would still use "Windoze". I'm sorry for my poor spelling. )
cl.exe is never pre-installed in Windoze. You can get cl.exe by the following ways: Download and install Microsoft Visual C++ Toolkit 2003 (gratis, outdated) Download and install Microsoft Visual C++ Express (gratis, seemingly crippled) Buy and install Microsoft Visual C++ (only this one has MFC support) ( I say Visual C++ Express is crippled because some of my friends once find that same program has significant performance downgrade in the Express edition. )
