How to edit registry, delete a file & start/stop a process using C & C++..?

[Subin Ninan]

I want to create an application using C or C++ which includes all these operations.

This is actually a Windows programming question and not anything to do with C/C++.

You should be able to find plenty of examples in MSDN just by using Google.

If you need a book, I suggest Windows via C/C++ by Jeffrey Richter.
