This is a Windows batch file named RunNotebook.cmd that will find the file called MakeMeIntoHTML.nb inside the same directory and convert it into an accessible HTML document with SVG graphics and serialized code, the output document is named ConvertedFromNB.html and is placed in the same directory as everything else. It would only take a small change to RunNotebook.cmd to make it possible to evoke the script from commandline and pass in the target notebook, but I found it easier to just put the target notebook into the directory and rename it.
The RunNotebook.cmd batch file works by launching a Wolfram Kernel and running the RunNotebook.wl Wolfram Script.
The RunNotebook.wl Wolfram Script simply opens a Wolfram FrontEnd and evaluates the RunNotebook.nb notebook.
The RunNotebook.nb notebook is where the magic happens and the HTML is created and exported.
