Do not display the ‘Shared files’ folder in the network(Windows XP, Vista, 7)

              Windows has released the ‘Shared files’ folder by default for all users, and as a result, it is visible even to the network. You want to prevent this, but it cannot be undone in a conventional manner.

              To deactivate the release of the ‘Shared files’ system folder, delete the relevant registry key. For that, open the registry editor with the command ‘Start | Run’ followed by the instruction ‘regedit’. In Vista and Windows 7, you can directly enter the command in the search field in the start menu. In the editor, navigate to the key ‘HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\NameSpace\DelegateFolders’. Under that, you will find the entry ‘{59031a47- 3f72-44a7-89c5-5595fe6b30ee}’. Right-click and export the key and specify a corresponding name, e.g. ‘Disable_Network_Visability.REG’ and click ‘OK’. Then delete the key and confirm at the following step. The change only takes effect after a restart.
NOTE: The relevant key only contains one empty REG_SZ value ‘(Standard)’. To later reactivate the release of the folder ‘Shared files’ in the network, recreate the key. For that, simply double-click the previously saved REG-file.
