my favorite feature of windows vista
 

The slide show displays each image in the folder in a presentation format on
your computer screen. Which is very handy when looking for a picture
quickly. You can view pictures by automatically moving through the pictures
or by using the navigation buttons to view the next or previous picture.
There is also a way to ajust the slide show speed which can be done by
clicking the options button located by the exit button. Another great
feature to slide show is that you can rotate, pause and exit the slide
show.
