I tried using the XP Event Viewer through the Computer Management mmc (right click the "Event Viewer" heading, select 'Open Log File') to open evtx file, but it said the file was corrupted. It seems to only recognize .evt files, not .evtx
I then used a Windows7 machine, select Start, search for programs and files for Event Viewer, and I was able to open the evtx file through there.
