ASD's Blueprint for Secure Cloud

Screen Saver

This section describes the design decisions associated with screen savers on Windows 10 and 11 endpoints configured according to guidance in ASD's Blueprint for Secure Cloud.

Estimated reading time: 2 minutes

The screen saver was originally designed to prevent burn-in on Cathode Ray Tube (CRT) and plasma screens. Modern usage of the screen saver enables the operating system to detect a period of inactivity and lock or blank the screen reducing power usage.

Screensavers should be applied at regular intervals in instances that a user may walk away from their endpoint and leave their workstation unlocked. Screensavers can also be used in some circumstances as a communication mechanism to users.

Microsoft does not recommend enabling a screen saver on devices. Instead, Microsoft recommends using automatic power plans to dim or turn off the screen as this can help reduce system power consumption.

Configuration can be applied to restrict the end-user ability to configure or change the screen saver settings.
