What's in YOUR wallet?

By "wallet", I'm referring to your CD wallet, or more specifically, your toolkit.

What tools do you use during Windows IR/CF activities?

What are your favorite/most relied upon tools for Windows Incident Response?

What tools to you use, in addition to the popular forensic suites (FTK, EnCase, PyFlag, ProDiscover, TSK, etc.) when analyzing a Windows system image, regardless of platform?

Finally, what tools would you like to see? What are some of the tools that you'd like to have that you just can't find? What are you trying to accomplish, specific to Windows IR/CF analysis, that you simply cannot find a tool to help you?

Think of this as a Windows IR/CF Top 75 Tools list. I'll accumulate responses here, and any I receive via email, and post the list.
