: I copied a code from msdn to get the system information. I tried to
: run it in TurboC3. But the error was "unable to find windows.h". I
: searched for it in Help but found no headerfile named windows.h. How
: can i load windows.h? is there a possibility of loading it or
: suggest some other means
TC3 is very old compiler and it will not support code using <windows.h> - if the program is for windows, of course. You need a compiler for Windows - you can get the free Dev C++, for example.
