If you set the log_level to debug and restart the Windows agent running as a service,
C:\> puppet config set log_level debug --section main
C:\> puppet config set logdest C:\Users\Administrator --section main
Then the Windows agent will log a deprecation warning each time it runs due to calling `puppet agent --configprint runinterval`. It should instead call `puppet config print runinterval --section agent`.
