Windows: Enable screen protection by default to block screenshots, recordings & Windows Recall. Add configurable setting in Preferences, Installer, and MSI.

Browse Source 
This update introduces a screen protection mechanism that leverages the Windows Display Affinity API to prevent screen capture, screen recording, and inclusion in the Windows 11 Recall feature. By default, all VeraCrypt windows, menus, and tooltips are protected. Users can enable or disable this feature through a new setting available in the application Preferences, as well as in the installer and MSI configurations.

This enhances user privacy by mitigating potential leaks of sensitive interface content.

Note: Due to a regression in Windows 11 affecting layered windows, ComboBox dropdowns cannot currently be protected by this mechanism.
