alt Hacker NewsWinDbg is just a debugger: it does not assemble or disassemble. It can't patch running programs in memory. Moreover, I don't consider Windows to be part of the modern era, as I haven't used a Windows machine for 20 years.
So, no, WinDbg has nothing to do with debug.com.
Fun! So how was OP supposed to know your very personal and weird definition of what is part of the modern era?
