Loaded Modules

If the reader directs attention to the Command window it is noticed that a series of modules are loaded and the WinMine process has been issued a break.

ModLoad: 01000000 01020000   C:\WINDOWS\System32\winmine.exe
ModLoad: 77f50000 77ff7000   C:\WINDOWS\System32\ntdll.dll

The two 32-bit addresses following "ModLoad:" represent the virtual memory address range the corresponding module is mapped to. These loaded modules contain functionality that WinMine is dependant upon. To get a list of loaded modules, the reader may issue either of the following commands: lm, !lm, !dlls

The reader should also notice that WinDBG, by default, articulates register values within the Command window upon reaching a breakpoint or at the completion of each step.
