What does one do if they have forgotten the password to their computer?

o.<

Here's the story.

For the past year, I have been using different passwords all from the same genre: Betrayal in a Bottle, my in-progress-almost-done story (the first few chapters of which are located in my gallery). They have thus far all been names of a character NOT demetri -- the password hint is "Demetri and"

I typed in every single character name, even one-chapter-cameo characters, their last names, all caps lock, various variations of typos... nothing. I've even tried Demetri, characters from Twilight, and passwords for other things that I use. NOTHING.

And what is tre suck is I JUSTJUSTJUST scanned a bunch of pics that I wanna post D<

So what does one do in this situation? Keep in mind I have Windows XP and I am the Administrator of the computer.
