Datadog Trace Agent for Windows

The Datadog Trace Agent is now available for Windows users. By default, the agent is not enabled so you have to start it manually as a Windows Service, or add apm_enabled=true in your datadog.conf to start it automatically.

Windows caveat

When the trace-agent is installed and it's running, the Datadog Agent service can only be stopped and restarted through the Windows Service Control Manager or the net command-line utility. Stopping and restarting the Datadog Agent service from the Agent Manager GUI does not work.
