title: TFS Compare freezes visual studio
body: <p><strong>ISSUE</strong></p>
  
  <p>While in VS, right-clicking on a file and selecting "Compare" will completely lock up Visual Studio.</p>
  
  <p>The same happens when right-clicking inside the text-area of a file and doing a Compare.</p>
  
  <p>The same happens regardless of file type... I've tried with .js .vb .cs .ascx .css</p>
  
  <p>Attempting to click anything in the UI, including the minimize or close buttons, does absolutely nothing. The buttons don't even highlight to show hover / focus.  The only way to close VS is through Task Manager.</p>
  
  <p>Other staff with the same spec laptop as me, same version of programs, and same VS solution... are able to Compare just fine.</p>
  
  <p><strong>SPECS</strong></p>
  
  <p>Visual Studio 2017 Enterprise</p>
  
  <p>Team Foundation Server 2015</p>
  
  <p>Windows 10 Enterprise</p>
  
  <p>16 GB RAM / i7 1.99 GHz processor</p>
  
  <p><strong>TROUBLESHOOTING</strong></p>
  
  <p>I've seen some suggestions of disabling "Identify Helpful Extensions" in Options => Text Editor => HTML => Advanced.  No change.</p>
  
  <p>I've restarted the Windows server that TFS is hosted on.</p>
  
  <p>No events are logged in Event Viewer Application or System.</p>
  
  <p><strong>ADDITIONAL NOTES</strong></p>
  
  <p>With a solution already open, VS is currently consuming 0 CPU and between 220 MB and 240 MB of memory.  When I attempt to Compare a file with TFS, and TFS immediately becomes frozen, the Memory remains mostly stagnant. Occasionally going up or down a few MB over the course of minutes.</p>
