If you deleted any of the default libraries, you can recreate them one at a time, but there’s a much easier way to get back the default libraries that come with Windows 7.
1. Click on the Windows Orb on the taskbar. Open your Libraries folder.
2. Go to the Navigation Pane, right-click the desired Library and select Restore Default Libraries.
The libraries that came with Windows 7 will be recreated.
