Windows Spotlight is a function that automatically changes the image of lock screen. This is like a lock screen version for PC of automatic change of image image which the Microsoft search engine "Bing" already has on Windows Phone or Windows tablet.


Windows Spotlight allows you to activate optional features when users desire, so it is up to the user whether or not to use the feature.

Windows Spotlight recommends not only image images, but also you can suggest store apps etc. from users' application usage trends.
