title: DISM /Import-DefaultAppAssociations runs successfully, but no file associations are changed
body: <p>On Windows 10, I run</p>
  
  <pre><code>dism /online /import-defaultappassociations:\\path\to\appassociations.xml
  </code></pre>
  
  <p>The output says the command was completed successfully, but the defaults aren't changed when opening files. The changes are also not visible in <code>Control Panel &gt; Default Programs</code>.</p>
  
  <p>I know the xml is accessible and this command worked on 8.1 computers in our environment. But every Windows 10 computer has had the same issue.</p>
  
  <p>The DISM logs show some warnings, but I cannot really tell if they are related. I can provide them if necessary.</p>
