In case you have to do it manually like I have to on a few of my IIS web servers, but you’re not sure how to do so, here’s how (from WordPress.org).
- Download the latest WordPress zip (or tar.gz) file from http://wordpress.org/download.
- Unpack the zip file that you downloaded.
- Using an FTP client, upload the new wp-includes and wp-admin directories to your website, overwriting old files.
- Upload the individual files from the new wp-content directory to the existing wp-content directory in your website, overwriting existing files. Do NOT delete your existing wp-content directory. Do NOT delete any files or directories in your existing wp-content directory (except for the one being overwritten by new files).
- Upload all new loose files from the root directory of the new version to your website root directory.
- Using a web browser, go to http://www.yourdomain.com/wp-admin. You may be asked to log in.If so, enter your WordPress login information, then click Log In.
- If a database upgrade is necessary at this point, WordPress will detect it and give you a link to http://www.yourdomain.com/wp-admin/upgrade.php. Follow that link and follow the instructions. This will update your database to be compatible with the latest code.
- In the WordPress dashboard, select Settings >> Permalinks.
- Click Save Changes.
These are the exact steps I used in the user manual I gave to my customers who unfortunately had to do so because they’re hosted in a very strict Windows-based network running on Microsoft’s Internet Information Server.
