This post does basically the same thing that I have already covered in my “WordPress on IIS 8.5 (Windows 2012 R2)” post, but it is a script that does literally everything for you. You will just need to add in a few of your own settings into the script, run it, and you will have a functional WP site.

First lets start of with the Features that I already have installed:

You will most likely have all of these but Telnet… INSTALL TELNET!

NOTES:

• Use https://api.wordpress.org/secret-key/1.1/salt/ to generate your Salt Keys… After they have been generated, you must replace any “$” character with any other character. Not just this script, but WordPress will not work if there is a “$” character in the salt keys.
• You will be asked for some variables, they are as follows:

• You can download check out the progress of the script on my Github and you can download it with the following icon:
