title: Need to disable "open , save , save as prompt" while opening pdf in IE11
body: <p>I have tried searching for an answer and it was said that, we need to do the following:
  1. click on the file and click on save when prompted.
  2. open IE11 ->tools->view downloads.
  3. Right click on the pdf file and uncheck the checkbox for "Always ask before opening this type of file"</p>
  
  <p>How ever in my system, I do not get this option for pdf, though I get this option for excel file(.xls). In another system where I need to remove this prompt, I do not get this option either for .pdf or .xls</p>
  
  <p>Some extra information:</p>
  
  <p>I have the adobe pdf reader add-on enabled in manage add-ons.</p>
  
  <p>I tried merging the following into registry</p>
  
  <p>Windows Registry Editor Version 5.00</p>
  
  <p>[HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute{0002DF01-0000-0000- C000-000000000046}]<br>
  "AcroExch.Document.DC"=hex(0): </p>
  
  <p>as I get .pdf=AcroExch.Document.DC when I type assoc.pdf into cmd</p>
  
  <p>So my question would be </p>
  
  <p>1.how to get this option on right clicking a file in IE11->tools->view downloads</p>
  
  <ol start="2">
  <li>Is there any other way to disable the prompt while opening pdf in IE11</li>
  </ol>
