I want to see what's going on backstage. Where does MiKTeX write the trace messages?

MiKTeX programs log their actions into the DebugView window, if you specify suitable trace options.

How do I use the DebugView window?

First of all, you will need the DebugView utility. To download DebugView, visit the DebugView page and follow the download/installation instructions.

How do I set trace options?

Set the environment variable MIKTEX_TRACE. The value must be a comma-separated list of trace stream names. For example,

set MIKTEX_TRACE=error,access

will trace all errors and file accesses. For more information, read the section Trace Streams in the MiKTeX manual.
