I'm the dev lead for WinDbg and the windows debugging platform, and I'm a former dev working on time travel debugging (I wrote the cpu emulation for the project). Happy to answer any questions that anyone has. Since I'm "posting too fast", let me put my answers here for now: qod: Right now you can attach TTD to a process after initialization (or any point in time prior to the repro), but you can't trace starting from a breakpoint. We'd love to add that functionality though, so I'm sure you'll see it in a future version of the tool. Glad you like the new WinDbg! It's been very polarizing (which you can see just reading the comments on this post!), so it's good to hear the positive feedback sometimes :) We've got a ton of plans to make debugging even faster and more effective in WinDbg, so hopefully we'll win more people over as we make our tools easier to use and more powerful.

First I would just like to say how impressed I am with the new WinDbg and TTD, this is fantastic work and a huge improvement on the existing debugging tools. My question is: if I want to start taking a TTD trace after hitting a particular breakpoint in WinDbg, can this be done with the current tooling? Use case would be if there is a large amount of initialization code that doesn't need to be traced because the bug or crash is known to occur at a later stage in the program.
