Ensure 'Make hidden markup visible' is set to 'Enabled'

AltaNivel 1Automatizadaoffice

Descripción

This policy setting controls whether hidden markup is visible when users open PowerPoint files in standard or HTML format. The recommended state for this setting is: Enabled. Rationale: If a file is saved with hidden markup, users might inadvertently distribute sensitive comments or information outside of their trusted circle without realizing that this information is still present in the document. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\powerpoint\options:markupopensave (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.
