I stopped playing long ago and don't have that particular computer anymore, but I used to have a really high streak somewhere over 1000.
I'm not that great, but I figured out that if I got stuck in a game and then hit control-alt-delete to open the task manager there was a way to exit the game without it counting as a loss.
Once I figured out that trick I never lost again. Not sure if it still works or not on current Windows whatever.
And, geez, who the hell still plays Freecell? Is this 1997? Maybe it ten years you guys will discover Angry Birds.
