But when I tried to set title through "START" command in cmd, command prompt window title getting changed instead of PowerPoint viewer window. If any one have idea please help me out.

It's not a common thing to want to change the title of a program window - only a cmd window - and that is what the title command and the window title field in the start command is for.
