Ensure 'Disable All ActiveX' is set to 'Enabled'

AltaNivel 1Automatizadaoffice

Descripción

This policy setting controls whether ActiveX controls are disabled across Microsoft Office applications. The recommended state for this setting is: Enabled. Rationale: Without this setting, users can change the ActiveX trust level in the Trust Center of Microsoft Access, PowerPoint, Word, and Excel, and untrusted controls are presented in the Message Bar for the user to allow or block. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\common\security:disableallactivex (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.
