I am afraid that I am one of the poor men using Micro$oft Debugger, because most of my tasks are programming oriented ...

For developing drivers or reverse engineering, SoftICE or OllyDbg might be better, since they are binary oriented; I dunno if there is other feature that I have missed ...

Micro$oft Debugger does not have enough features for a cracker, like the memory search in SoftICE, so unless you can kick it go, or use the remote debug feature to debug the kernel of WinXP/2k etc, you may find it almost useless ...
