It's your operating system, not an advertising platform!
Microsoft is turning Windows 10 into an advertising platform and the ability to disable these ads are hidden in different menus, require Pro/Enterprise versions, or can't be disabled at all...but with a single click, SnapBack Apps takes care of all of them.
Which Ads will be disabled?
Without SnapBack Apps there is no way to disable ads on your Windows Spotlight lock screen
(The only option is to disable Windows Spotlight completely...)
