title: How possibly did IntelliTrace become available on my Visual Studio Professional installation?
body: <p>As described in some other Q/As like <a href="https://stackoverflow.com/q/17153023/450913">this</a> and <a href="https://stackoverflow.com/q/2666231/450913">this</a>, IntelliTrace is a Visual Studio Ultimate feature only. But for some reason I have Visual Studio Professional 2013 (Version 12.0.30723.00 Update 3) and I have IntelliTrace on it. I don't know how it got there but it shows up in Quick Launch (Ctrl+Q) and is enabled from <strong>View -> Toolbars -> IntelliTrace</strong>. I told my colleague to use it and he didn't have it on his VS Pro! Do you have any clues why IntelliTrace is available on my VS 2013 Pro installation? I see comments from other people, such as @doglin <a href="https://stackoverflow.com/questions/17153023/intellitrace-not-available-for-vs-2012-professional-edition#comment24831505_17153315">here</a> that he has the same.</p>
  
  <p>I remember I had VS Ultimate trial installed before I installed VS Pro but can it be from there?</p>
