"Invisible" Window feature not working (FindWindowA returns null?)

[SimonKaluza]

Describe the bug Setting the "invisible" macro does not correctly hide the console window. i.e. the ShowWindow(FindWindowA("ConsoleWindowClass", NULL), 0) call on line 161 of klog_main.cpp doesn't seem to have any effect.

To Reproduce Steps to reproduce the behavior:

1. Create a new VS 2019 command-line CPP project
2. Paste the entire code of klog_main.cpp
3. Change #define visible to #define invisible
4. Command-line window showing Keylogger still remains open after compiling/running successfully.

Expected behavior We expect the command-line window to be hidden, but it seems the call to FindWindowA("ConsoleWindowClass", NULL) returns null, which means the subsequent call to ShowWindow has no effect.

There exist HWND WINAPI GetConsoleWindow(void); to get the console window of the keylogger, it works, although, windows defender might flag the build as a Trojan/Keylogger.

I added the FreeConsole(); call after ShowWindow(FindWindowA("ConsoleWindowClass", NULL), 0); // invisible window which resolves this concern. I submitted a pull request with the change. Hopefully it is accepted as a solution.
