title: What config file does appcmd.exe update?
body: <p>When running <code>appcmd.exe</code> commands from the command prompt, is there a config file getting updated somewhere? If so, where is that file?</p>
  
  <p>For example, I ran the following:</p>
  
  <p><code>appcmd.exe set config "MyWebsite" -section:system.webServer/modules -runManagedModulesForWebDavRequests:true</code></p>
  
  <p>It's great that running the command solved my problem, I just don't know what actually changed? Is this a setting I can see from within IIS or was there a config file somewhere that changed? I thought I'd see the <code>ApplicationHost.config</code> file get updated, but that wasn't the case.</p>
