Ensure 'Excel 4 macrosheets and add-in files' is set to 'Enabled: Open/Save blocked, use open policy'

Opis

This policy setting determines whether users can open, view, edit, or save Excel files with Excel 4 macrosheets and add-in file format. Open/Save blocked, use open policy: Both opening and saving of the file type will be blocked. The file will open based on the policy setting configured in the "default file block behavior" key. The recommended state for this setting is: Enabled: Open/Save blocked, use open policy. Rationale: Using legacy file formats could allow malicious code to become active on a user's computer or the network. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\excel\security\fileblock:xl4macros (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 2. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.
