A new enhancement has arrived for select users of Microsoft's free Windows 10 operating system. While the screen is locked, an offer for the popular game Rise of the Tomb Raider [wikipedia.org] (buy it here [archive.org]) is displayed.
The free game posters may, for now, be disabled in the lock screen settings by turning off both Windows Spotlight and the option to “Get fun facts, tips, tricks, and more on your lock screen.”
