email recovery

I need to use my account recovery code and don't know how to go about doing that. It was for a live.com account that I had used to log onto computer and had to jump through hoops to get access back to computer after a week or so. Now I find the code written on a lil piece of paper folded up that just fell out of my wallet the other day.LOL  I think my wife had gotten it out when I was asleep and later put it back. Yeah I know. But could someone step me thru what I need to do now to recover my email  please? I am dumb as a rock and don't know what the process is to go about doing that.  Thanks.
