Ensure 'VBA Macro Notification Settings' is set to 'Enabled: Disable all except digitally signed macros'

高レベル 1自動office

説明

This policy setting controls how the specified applications warn users when Visual Basic for Applications (VBA) macros are present. The recommended state for this setting is: Enabled: Disable all except digitally signed macros. Rationale: By default, when a user opens a file that contains VBA macros, the macros are disabled, and a warning is displayed on the Trust Bar that the macro has been disabled. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\publisher\security:vbawarnings (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 3. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.
