it will work on window 7 but not window XP, it doesnt work.
you take videos on camera while riding or any place for fun.
plug it to laptop or computer, wait a few seconds till it pop up on computer and click import all the videos, pictures, it will save all in your computer.
If you want to do some video editing, I use Windows live Movie Maker.
when finish editing, save it, then upload to youtube from windows live movie maker, faster than getting from documents library (take forever).
you should practice with gopro camera before you go out ride so you can get used to it.
