title: Finding a window when only part of the window title is known in Coded UI Tests
body: <p>The application I am writing coded UI tests for has a window where part of the window title is based on a random filename generated for a temporary file, so the test can only know the static part of the window title.</p>
  
  <p>Occasionally, when no other windows are open, the test runs fine.  It is a bit problematic when other windows are open, however.  If the other windows have similar controls, which window the test picks to work in is unpredictable.</p>
