LongBar

Although latest Windows versions come with a widget sidebar, there are some alternative bars that can help us when decorating our desktop and, at the same time, have some useful extra features.

LongBar, is a free and open source sidebar that integrates itself perfectly in the Windows desktop.

Choose the tiles you want to add to your new sidebar: clock, weather, Facebook, Twitter, system tray, Media player, etc.

Finally, you can change the look of the sidebar thanks to the theme support.
