title: Microsoft Edge F12 Developer Tools don't open
body: <p>After upgrade to Windows 10, I can't get the F12 Developer Tools to show / work under MS Edge.</p>
  
  <p>IE 11 developer tools do still work, but I can see rendering differences on my websites I am working on between them, so could do with getting them working under Edge.</p>
  
  <p>I am presuming they are available??</p>
  
  <p>Have already tried the re-register packages fix, as well as reset Internet Options, but nothing works.</p>
