Ummmm... FindWindow is a Win32 C function. It returned NULL because it most likely did not find a window named "Windows Task Manager". Read up on the API documentation.

Try using EnumWindows function. It sends you the information from all the current windows. Then you will see if you have a window titled "Windows Task Manager"

This is a windows (win32) API programming question, not a C question.

FindWindow() returns NULL if it can't find a window matching the supplied arguments.

And yes, are you sure that the Windows Task Manager was even open when u ran this program ???
