Hosting – Linux or Windows?
You’re setting up a WordPress Website. You’ve chosen shared hosting but the host asks if you want Linux (also called Apache hosting) or Windows (also called IIS hosting).
You’ll never be logging in or managing the server itself so it makes no difference if you’ve never seen Linux. What does matter however is that Linux Apache is very widely used whereas Microsoft IIS has a far smaller market share. Most WordPress Themes and Plugins are tested on Apache so it is generally far preferable to choose Linux hosting.
