Free Windows 7 Screensaver is a beautiful screensaver that includes a bunch of images of landscapes to enjoy. It shows the images using random effects, which you are not allowed to customize. The images are really beautiful and relaxing, but there is no music nor sounds, which is a shame, since they would surely improve the screensaver's quality. Unfortunately, the images won't fill the screen, so you will have black spaces on the sides and a title showing the screensaver's source that cannot be eliminated. You can customize the effect time, but you cannot select the time the slides remain on the screen. You can set the screensaver to show a clock and slide number, selecting their position, size, format, and color. If you want, you can also export the images included in the screensaver by using the export files button, so you can use the images for something else.
In short, Free Windows 7 Screensaver is a nice screensaver with many beautiful pictures to enjoy, but which lacks many features that would make it more attractive.
