Ensure 'Disable Trust Bar Notification for unsigned application add-ins and block them' is set to 'Enabled'

Опис

This policy setting controls whether the specified Office application notifies users when an unsigned add-in is loaded, or silently disables the add-in without notification. Note: This setting only applies if you enable the Require that application add-ins are signed by Trusted Publisher policy setting, which prevents users from changing this policy setting. The recommended state for this setting is: Enabled. Rationale: Allowing unsigned application add-ins could cause the application to load dangerous add-ins and as a result, malicious code could become active on user computers and the network. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\excel\security:notbpromptunsignedaddin (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 1. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.
