title: MSTest is removing Test Results when VS2013 is running as Administrator
body: <p>I know that sounds strange but that is how it is)</p>
  
  <p>I'm using MSTest to run my unit tests.
  Using VS2013 + ReSharper 8.1 + some dll projects in C#.
  I'm calling some API functions, that is why I need VS to running as Administrator or those calls will fail.</p>
  
  <p><strong>The problem is:</strong></p>
  
  <p>For some reason folder TestResults is empty.
  While tests are running and not completed, I can see a new folder (User_Comp YYYY-mm-dd HH-MM-ss) created inside, with all test outputs, but once tests are completed this folder is deleted, so TestResults are empty.</p>
  
  <p>I've checked my project Options->Web Performance Test Tools->Test Execution->Limit number of old Test Results is set to 25.
  I've tried to disable ReSharper UnitTesting + disabled support for MSTests, NUnit and JS, but problem still exists.</p>
  
  <p><strong>When VS is started under normal account (not Administrator)</strong></p>
  
  <p>In this case folder "TestResults\User_Comp YYYY-mm-dd HH-MM-ss" is not deleted after test. Of course in this case some of my tests are failing.</p>
  
  <p>I've set full access for each user to folder "TestResults" but still results are removed.</p>
  
  <p>Looks that VS is using 0 as limit for Test Results.
  Did anyone face this problem?</p>
