Making Pi3web not start automatically at bootup

["Wall, David K." <dkw0@cdc.gov>]

I use Pi3web occasionally, but not every day.  It's set up to start
automatically when I boot the computer.  How can I set it up so that I have
to start it manually?  I've looked through the docs, but haven't been able
to find anything.  Pi3web isn't in the Startup folder in the Start menu, and
I've not found anything in the registry, although I'm not certain where to
look.  Any suggestions?
