An anonymous reader quotes a report from The Verge: Microsoft is working on a new Windows 10 feature that will automatically lock and secure a PC when the operating system detects someone has moved away from the machine. The feature is labelled as Dynamic Lock in recent test builds of Windows 10, and Windows Central reports that Microsoft refers to this as "Windows Goodbye" internally. Microsoft currently uses special Windows Hello cameras to let Windows 10 users log into a PC with just their face. Big corporations teach employees to use the winkey+L combination to lock machines when they're idle, but this new feature will make it an automatic process. It's not clear exactly how Microsoft will detect inactivity, but it's possible the company could use Windows Hello-compatible machines or detect idle activity and lock the machine accordingly. Windows can already be configured to do this after a set time period, but it appears Microsoft is streamlining this feature into a simple setting for anyone to enable. Microsoft is planning to deliver Dynamic Lock as part of the Windows 10 Creators Update, expected to arrive in April.
