Microsoft along with Windows 8 Consumer Preview, also published a theme that showcases some of the new desktop theming features available in Windows 8. In a blog post, Jennifer Shepherd detailed Windows 8 themes features including: panoramas, auto color, and more.
Shepherd notes "themes created in the Windows 8 format will not work in Windows 7," because Windows 8 introduces a few new desktop personalization features that aren't supported in Windows 7, and the file format is different.
Writing further, Shepherd talks about the new "panoramic theme" feature that allows a theme to be seamlessly shown across dual monitors with identical resolution settings. "If the displays are different sizes or have different resolution settings, the panorama will not automatically extend across both monitors. Instead, a different image will appear in each display," Shepherd explains.
Incidentally, you don't need to have a dual monitor setup to use a theme that contains panoramic images. If you have only one monitor, each image will be cropped to the center. So those of you without multimon can still enjoy the images in the Windows Personalization Gallery's very first Windows 8 theme, Nightfall and Starlight, said Shepherd.
Shepheard also highliths another new feature - also aimed at dual monitor setups: "Themes containing regular-size (non-panoramic) images will display a different image in each monitor, instead of just duplicating the same image, as occurs in Windows 7," Shepher said. Windows 8 actually does this automatically, even with Windows 7 themes.
Another cool feature in Windows 8 is the auto-color feature. "Windows 8 themes created with the auto color setting will smoothly and automatically shift the Windows desktop glass and taskbar color to match the dominant color in whichever background image is currently being displayed," Microsoft adds.
