- save the file as Admin.evtx
- zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
- upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).
FYI - If we're looking for Event ID 41 errors (unexplained shutdowns), there's more info on that here:
