Implementation of the program startup from Windows by writing the registry

The program can read the configuration in the Config.ini file in the same directory to enable boot.

The Config.ini file format instance is as follows:

[Main]
KeyName = Test
Processpath = D:\bin\test.exe

Where the KeyName field is the table key name written to the registry (can be set to the program name)

Processpath the full path to the program

The complete source code for the program is as follows.

The Regedit function implements the registry write, and the autopen implements the boot from boot.
