Use Windows Debuggers for Non-Debugging Tasks

Sharing a similar spirit as Emacs, Windows Debuggers are also super good at non-debugging tasks.

Calculator

The builtin expression evaluator of Windows Debuggers can be used as a handy calculator:

0:000> ?? 1+2+3
int 0n6

0:000> .formats 0x00905a4d
Evaluate expression:
  Hex:     00000000`00905a4d
  Decimal: 9460301
  Octal:   0000000000000044055115
  Binary:  00000000 00000000 00000000 00000000 00000000 10010000 01011010 01001101

Process Manager

I try not to use the term Task Manager, since the name is already occupied by taskmgr.exe, and we have nothing to do with tasks (taskmgr also has nothing to do with tasks).

0:000> .tlist -v windbg*

Shell

0:000> .shell tlist -t

0:000> .shell dir

Binary Editor

The basic idea is to load a portion of file data into the address space of a debuggee, perform some inspection or modification, then write back to the file. WinDBG even has a Memory Window, which makes it a perfect GUI Hex Editor!

To examine the file information such like name, permission and size, use the .shell command.

0:000> .shell dir *.netmodule
