Assessment Title

Rule Text

Status bar updates via script must be disallowed (Restricted Sites zone).

Description

Discussion Text

A script running in the zone could cause false information to be displayed on the status bar, which could confuse the user and cause an undesirable action. This policy setting allows you to manage whether script is allowed to update the status bar within the zone. If you enable this policy setting, script is allowed to update the status bar. If you disable this policy setting, script is not allowed to update the status bar. If you do not configure this policy setting, status bar updates via scripts will be disabled.

if (Test-Path $regPath) {
