I will not read your code next time if you don't read this: http://cplusplus.com/forum/articles/16853/

1. This is the most pointless C based program I've ever seen.
2. The main definition is 'int main(void)' or 'int main(int, char**)', not 'void main(void)'.
3. Most of your headers aren't needed.
4. The use of system() makes me lol.

Easy Suggestion: Make a batch script instead of making an entire C++ application if you want to use commands to edit registry keys.

Intermediate Suggestion: Use calls to the WinAPI to change the registry natively.

Difficult and Opinionated Suggestion: Don't use the registry as it's an embarrassment to mankind.

there's also an odd 'i' before main in your code
