title: How to upgrade Apache on a Windows server?
body: <p>I have just upgraded our webserver from PHP 5.3.6 to 5.3.10, and I now want to upgrade Apache as well from 2.2.17 to 2.2.22 (on a <strong>Windows Server</strong>). How do I go about this in a good way (on a live webserver)? A little downtime is alright, but not too much.</p>
  
  <p>Apache is installed via an MSI installer and I'm not sure how to upgrade safely with the least downtime.
  Do I just download the latest installer and install that? And what about my config files? I don't think it's possible to have both instances installed 'next to each other'? Or is it?</p>
