Note that this registry setting controls a default, meaning that it only affects console apps which don't explicitly manipulate the console mode by calling SetConsoleMode(.). Create a DWORD key (if necessary) and set its value to 1 to globally enable (or 0 to disable`) ANSI processing by default. The registry key at HKEY_CURRENT_USER\Console\VirtualTerminalLevel sets the global default behavior for processing ANSI escape sequences. But many other tools or executables that write to stdin or stdout might not do this, in which case you won't see color for those processes.įortunately, the global default can be changed from opt-in to opt-out. I'm guessing the reason the examples shown on this page work is that, apparently the echo command (or perhaps the batch-processing part of CMD.EXE or conhost) enables ANSI processing by calling the API just mentioned. For more information, see Console Virtual Terminal Sequences. When writing with WriteFile or WriteConsole, characters are parsed for VT100 and similar control character sequences that control cursor movement, color/font mode, and other operations that can also be performed via the existing Console APIs. Unless the specific software you're using enables ANSI processing by calling the SetConsoleMode API with the ENABLE_VIRTUAL_TERMINAL_PROCESSING (0x0004) flag, you won't see colors or get ANSI processing for that application.ĮNABLE_VIRTUAL_TERMINAL_PROCESSING 0x0004 Namely, it's n̲o̲t̲ e̲n̲a̲b̲l̲e̲d̲ by default. None of the answers on this page mention an important aspect of the new support for ANSI Terminal Control which was added to the Windows 10 console host in build 16257 (and later).
