When you download .bat files off the net, you can review them first, by

I think you meant to say you can review them by opening them in a text
editor, such as Notepad. No need to change the extension, even
temporarily. Right clicking should provide an 'Edit' context menu.

The first time I downloaded renewusb.zip,
I extracted renewusb.bat and changed the extension on the file, to
renewusb.bat.txt, so I could open the file with Wordpad or Notepad.

As above, it's not necessary to change the extension.

Take a few moments, to review the code and get a general understanding
of how it works. Sometimes, there are developer notes inside the bat
file, warning about certain things. Once you're happy the .bat file
is safe looking, you can change it back to renewusb.bat again,
before running it. I try to run stuff like that from a Command Prompt
window, so I can review the output while it runs.

I agree with running them from a command prompt so that any output can
be reviewed.
