    G’day – I ran according to instructions however:
    On restart the results were not shown
    Right clicking on start button does not bring up Event Viewer
    Did a search for event viewer but “no results found”
    Tried settings but couldn’t find it 🙁
    Any suggestions???

      I don’t know if you’re using Windows 10 or not. If you are and you have not replaced the Windows 10 start button with something like Classic Shell, right-clicking the Start button gives you the “power” menu which you can also get using the Windows key+ X shortcut. You can also type EVENT in taskbar search. On any version of Windows (Windows 7, 8.1, 10) you can press Windows Key + R to open a run box. Type eventvwr.msc in the run box and press Enter to start the Event Viewer.
