The toolbar upgrade tool will check to see if incompatible toolbars or browser helper objects are installed when Internet Explorer is launched. When detected the user will be prompted to update or disable the toolbar. Specific toolbars or browser helper objects that are enabled or disabled via policy will not undergo this check.
If this policy is enabled the toolbar upgrade tool will not check for incompatible toolbars. The user will not be prompted, and incompatible toolbars will run unless previously disabled through policy or the user.
If this policy is disabled or not configured the toolbar upgrade tool will check for incompatible toolbars. The user will be given the option to enable or disable incompatible toolbars. Toolbars that are enabled or disabled via policy will not undergo these checks.
