Remove DFS tab

This policy setting allows you to remove the DFS tab from File Explorer. If you enable this policy setting the DFS (Distributed File System) tab is removed from File Explorer and from other programs that use the File Explorer browser such as My Computer. As a result users cannot use this tab to view or change the properties of the DFS shares available from their computer. This policy setting does not prevent users from using other methods to configure DFS. If you disable or do not configure this policy setting the DFS tab is available.

Hide these specified drives in My Computer

This policy setting allows you to hide these specified drives in My Computer. This policy setting allows you to remove the icons representing selected hard drives from My Computer and File Explorer. Also the drive letters representing the selected drives do not appear in the standard Open dialog box. If you enable this policy setting select a drive or combination of drives in the drop-down list. Note: This policy setting removes the drive icons. Users can still gain access to drive contents by using other methods such as by typing the path to a directory on the drive in the Map Network Drive dialog box in the Run dialog box or in a command window. Also this policy setting does not prevent users from using programs to access these drives or their contents. And it does not prevent users from using the Disk Management snap-in to view and change drive characteristics. If you disable or do not configure this policy setting all drives are displayed or select the “Do not restrict drives” option in the drop-down list. Also see the “Prevent access to drives from My Computer” policy setting.

No Entire Network in Network Locations

Removes all computers outside of the user’s workgroup or local domain from lists of network resources in File Explorer and Network Locations. If you enable this setting the system removes the Entire Network option and the icons representing networked computers from Network Locations and from the browser associated with the Map Network Drive option. This setting does not prevent users from viewing or connecting to computers in their workgroup or domain. It also does not prevent users from connecting to remote computers by other commonly used methods such as by typing the share name in the Run dialog box or the Map Network Drive dialog box. To remove computers in the user’s workgroup or domain from lists of network resources use the “No Computers Near Me in Network Locations” setting. Note: It is a requirement for third-party applications with Windows 2000 or later certification to adhere to this setting.

If you disable or do not configure this policy setting users can open Folder Options from the View tab on the ribbon.

Hide the common dialog places bar

These policies only affect programs that use the standard Open dialog box provided to developers of Windows programs. To see an example of the standard Open dialog box start Wordpad and on the File menu click Open. Note: In Windows Vista this policy setting applies only to applications that are using the Windows XP common dialog box style.

Turn on Classic Shell

This setting allows an administrator to revert specific Windows Shell behavior to classic Shell behavior. If you enable this setting users cannot configure their system to open items by single-clicking (such as in Mouse in Control Panel). As a result the user interface looks and operates like the interface for Windows NT 4. 0 and users cannot restore the new features. Enabling this policy will also turn off the preview pane and set the folder options for File Explorer to Use classic folders view and disable the users ability to change these options. If you disable or not configure this policy the default File Explorer behavior is applied to the user. Note: In operating systems earlier than Windows Vista enabling this policy will also disable the Active Desktop and Web view. This setting will also take precedence over the “Enable Active Desktop” setting. If both policies are enabled Active Desktop is disabled. Also see the “Disable Active Desktop” setting in User Configuration -> Administrative Templates -> Desktop -> Active Desktop and the “Do not allow Folder Options to be opened from the Options button on the View tab of the ribbon” setting in User Configuration -> Administrative Templates -> Windows Components -> File Explorer.

Allow only per user or approved shell extensions

This setting is designed to ensure that shell extensions can operate on a per-user basis. If you enable this setting Windows is directed to only run those shell extensions that have either been approved by an administrator or that will not impact other users of the machine. A shell extension only runs if there is an entry in at least one of the following locations in registry. For shell extensions that have been approved by the administrator and are available to all users of the computer there must be an entry at HKEY_LOCAL_MACHINE -> Software -> Microsoft -> Windows -> CurrentVersion -> Shell Extensions -> Approved. For shell extensions to run on a per-user basis there must be an entry at HKEY_CURRENT_USER -> Software -> Microsoft -> Windows -> CurrentVersion -> Shell Extensions -> Approved.
