How to get rid of ads on the Windows 10 lock screen
Ads on your lock screen aren’t a totally new thing — we first saw them in February, when Microsoft started pushing the game Rise of the Tomb Raider. But since the Anniversary Update has nixed the registry hack that let Windows 10 Home users disable the lock screen — the policy that let Pro users kill it in the Group Policy Editor has also been cut — you may actually start noticing those ads.
You can still get rid of them (for now).
Yep, this is truly annoying BTW to even have to deal with this nonsense. But there it is.
Go to Settings menu > Personalization > Lock screen
From the Lock screen menu, you will need to choose Picture or Slideshow from your own computer for your Lock screen background and you will not have to deal with the ads.
If you choose Windows Spotlight images, you will have to deal with the ads sadly.
With one caveat from the article:
If you love the Windows spotlight wallpapers but not the ads, check out our guide on how to find and download past spotlight photos.
Thanks CNET. This should be very helpful to frustrated users.
