Turn off configuration of window reuse

This policy setting allows you to configure the behavior of new windows in Internet Explorer.

If you enable this policy setting, the user will not be able to configure the behavior of window reuse. You must specify whether links from other applications will:
• Open in an existing Internet Explorer window. If tabbed browsing is enabled, a new tab will be created in this scenario.
• Open a new Internet Explorer window.

If you disable or do not configure this policy setting, the user will be able to change window reuse.
