Applies proxy settings to all users of the same computer. If you enable this policy users cannot set user-specific proxy settings. They must use the zones created for all users of the computer. If you disable this policy or do not configure it users of the same computer can establish their own proxy settings. This policy is intended to ensure that proxy settings apply uniformly to the same computer and do not vary from user to user.

This policy setting allows you to configure how new tabs are created by default in Internet Explorer. If you enable this policy setting the user cannot configure how new tabs are created by default. You must specify whether tabs should open in the foreground or in the background. The user cannot open the tabs in the background by pressing Ctrl+Shift+Select or open the tabs in the foreground by pressing Ctrl+Shift+Select. If you disable or do not configure this policy setting the user can configure how new tabs are created by default.

This policy setting allows you to restrict the search providers that appear in the Search box in Internet Explorer to those defined in the list of policy keys for search providers (found under [HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE -> Software -> policies -> Microsoft -> Internet Explorer -> SearchScopes]). Normally search providers can be added from third-party toolbars or in Setup but the user can also add them from a search provider’s website. If you enable this policy setting the user cannot configure the list of search providers on his or her computer and any default providers installed do not appear (including providers installed from other applications). The only providers that appear are those in the list of policy keys for search providers. Note: This list can be created through a custom administrative template file. For information about creating this custom administrative template file see the Internet Explorer documentation on search providers. If you disable or do not configure this policy setting the user can configure his or her list of search providers.
