The new Digital Signage Mode introduced by Microsoft allows Windows to display system error messages, such as the Blue Screen of Death, for only 15 seconds before turning the screen black. This feature aims to prevent public visibility of technical errors on digital signage while still allowing support teams to address issues. The mode also applies to other disruptive Windows dialogs, but it is specifically designed for non-interactive public displays and does not extend to kiosks, which require direct user interaction. The mode can be enabled through the Windows Settings app or a registry key.
