Der Knoten Bibliothek selbst kann nicht ausgeblendet oder im Navigationsbereich von Windows Explorer gelöscht werden.
If certain default libraries are not suitable for the business environment (such as Music or Videos libraries), we recommend hiding those libraries. Hiding libraries is preferable to deleting them because many applications depend on these default libraries to run properly. Applications will re-create the default libraries if they cannot locate them on the computer.
To hide a default library, you need to run a script on the network to modify the Library Description file, and you need to set a Group Policy setting to hide the link to this library on the Start menu. The script should set the hidden attribute of the Library Description file (*.library-ms). This conceals the library from users in the Windows Explorer navigation pane and Items View. However, this does not hide the library in the Start menu or in the Include in Library option in the context menu. This also does not prevent the user from opening the library from an application or the Library application programming interface (API).
The following example script hides the Pictures library:
@echo off%systemdrive%cd\cd %appdata%\Microsoft\Windows\Librariesattrib +h Pictures.library-ms
You need to set a Group Policy setting for every library that has a link you want to conceal in the Start menu. You can find these Group Policy settings under User Configuration\Administrative Templates\Start Menu and Taskbar.
