title: Windows.old event viewer logs
body: <p>Is it possible to see old event log files, those that you can see in event viewer? But I only have windows.old folder available. </p>
  
  <p>Situation is that, that some of our company's computers were hacked. I want to check if mine was affected too.</p>
  
  <p>A few days ago I have updated windows 8.1 to Windows 10; now all event viewer logs are gone. But I have a <code>windows.old</code> folder with files on C: drive. How can I retrieve event viewer logs from there?</p>
