Time Travel Debugging (TTD) features now available in WinDbg Preview

WinDbg

Microsoft is introducing a very useful feature for its WinDbg Preview tool on Windows – Time Travel Debugging (TTD). Launched last month, WinDbg Preview provides great new debugging user experience and with the addition of TTD, users can go back in time to fix code problems, if any. This can help better understand the cause that leads up to the bug by repeatedly replaying it multiple times.

Time Travel Debugging (TTD) is a reverse debugging solution that allows you to record the execution of an app or process, replay it both forwards and backward and use queries to search through the entire trace.

TTD Features

  1. Record: Record the app or process on the machine which can reproduce the bug. This creates a Trace file (.RUN extension) which has all of the information to reproduce the bug.
  2. Replay: Open the Trace file in WinDbg Preview and replay the code execution both forward and backward as many times as necessary to understand the problem.
  3. Analyze: Run queries & commands to identify common code issues and have full access to memory and locals to understand what is going on.
