I made many changes to my machine so not sure if wget is available as a result of my changes or it always exists by default on Windows machines. Does it come with Windows
If not, what download function can I use in a Windows .bat script to download a file from the web. This function has to be available by default
Wget is not built into windows, however there is a windows version.
http://gnuwin32.sourceforge.net/packages/wget.htm
As far as I am aware, there is no similar built in dos command for windows.
