title: task scheduler is displaying an error "The specified query is invalid"
body: <p>I am running Windows 10.</p>
  
  <p>I'm trying to run a backup job (C:\WINDOWS\system32\robocopy.exe) using Task Scheduler. But I was getting issues. To figure out what was going on, I turned on the history log.  Unfortunately since doing that, every time I click the History tab I get the following error:</p>
  
  <hr>
  
  <blockquote>
    <p><strong>Dialog Title:</strong> "Query Error"</p>
    
    <p><strong>Dialog Message:</strong> "One or more logs in the query have errors."</p>
    
    <p><strong>The table in the dialog:</strong> "Microsoft-Windows-Task-Scheduler/Operational | The specified query is invalid"</p>
    
    <p>"The events displayed are partial results."</p>
  </blockquote>
  
  <p><strong>Nothing appears in the History pane</strong>, so I cannot debug either problem.  Does anyone know what is going on?</p>

  <p>The answer site (www.minasi.com) is apparently moved and did not retain the answer so cannot try the fix that solved his problem.</p>
