How to: Flag and Unflag Threads


This article applies to Visual Studio 2015. If you're looking for the latest Visual Studio documentation, use the version selector at the top left. We recommend upgrading to Visual Studio 2019. Download it here

You can flag a thread that you want to give special attention by marking it with an icon in the Threads, Parallel Stacks, Parallel Watch, and GPU Threads windows. This icon can help you and others distinguish flagged threads from other threads.

Flagged threads also receive special treatment in the Thread list on the Debug Location toolbar. This list can show all threads or only flagged threads. When you flag a thread, the Thread list automatically switches to show only flagged threads, but you can switch it back to show all threads as appropriate.
