Windows 7 users have the ability to disable sidebar and desktop gadgets from appearing on their screens. This can be done by opening the Control Panel, clicking on Appearance and Personalization, and then clicking on the Screen Saver tab. From here, users can select which gadgets they would like to disable. ..
If you are really, really new to Windows 7, the gadgets are accessible via the desktop context menu, and can be dropped anywhere on the desktop you’d like.
Note: If you are running Windows Vista, you can disable the sidebar there as well.
