Win7 does not seem to have sidebar function, only gadgets, in fact, the sidebar function is present, and will take up some system resources.

Open the registry editor, find the HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun branch, find and delete the "Sidebar" key-value item in the right window.

or run the System Configuration Utility msconfig, disable the sidebar keys to start the project.
