Windows lost my taxes

I did most of my taxes a week or so ago, and had a few things to finish up. I left the program running as a reminder to work on them. Apparently I forgot to save. Now, I am, of course, stupid for leaving it up without saving, but this could have been avoided. Anyway, sometime between now and then Windows decided to install some updates and reboot itself. Last night I went to put in a few finishing touches, and my taxes were completely lost. Needless to say, Windows sucks. I don't have any exciting screen shots or anything, but I am mad!
