It's because most people don't have the C++ Runtime library's.
If you want to build them right into your program, at the expense of the size (just a small increase of like 30-40kb) you can switch the project settings.
Project Settings
- C/C++
-- Code Generation
--- Runtime Library : Multi-Threaded (/MT).
Will build them straight into the project.
By default they're at Multi-Threaded DLL (/MD).

Or you can always be cool and just not use it at all, though depending on what functions you use, you may have to reinvent the wheel.

| everytime when you create a new program, it's a good idea to test it in debug mode first. In debug mode, it makes things easier for you to find errors. When you're confident that your program has no errors, then re-complie it in release mode. Release mode = uses less memory and resources btw.

You forgot to mention the massive size reductions.
