Fun! So how was OP supposed to know your very personal and weird definition of what is part of the modern era?

If OP wanted to know whether WinDbg and debug.com can be considered feature-similar, they could have read my first comment [1], where I specifically said that debug.com is a "debugger, *assembler*, and *disassembler*". Of those three features, WinDbg provides one.
