If the console window has a full eight-digit handle my custom printf would get stuck in a loop, causing CMD to seemingly freeze. Do what I really should have done in the first place and make it more robust.
ANSICON 
ANSICON provides ANSI escape sequences for Windows console programs. It
provides much the same functionality as ANSI.SYS does for MS-DOS.
Requirements
- 32-bit: Windows 2000 Professional and later (it won't work with NT or 9X).
- 64-bit: AMD64 (it won't work with IA64).
How it Works
ANSICON injects a DLL into a process, hooking its functions.
Injection
One of three methods is used to inject the DLL.
-
LoadLibraryviaCreateRemoteThreadfor a running process. -
LdrLoadDllviaCreateRemoteThreadfor a 64-bit .NET AnyCPU process. -
Adding the DLL directly to the import table, otherwise.
Hooking
Hooking is achieved by modifying import addresses, or the return value of
GetProcAddress.
