I'm using windows 10, and in the lock screen I see very nice scenery wallpaper. I'm trying to grab those jpg files so I can manually set them as my desktop wallpaper too. Doing this seems well documented, as in this previous thread. Also, a google search shows many sites also pointing to
C:\Users\myname\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets. We're supposed to go to that directory, and copy and rename the largest files there to jpg, then we have the scenery pictures and can do whatever we want with them.
Now it's fall 2018, and it appears there's one issue: that directory still contains files, and they are pictures when renamed to jpg, but the issue is that the largest file is 150 kb, and they are just a bunch of gaming art, candy-crush saga, stuff like that. There's no wallpaper there. From this cnet guide from 2016, which contain screenshots of that directory, it appears that previously, some of the files in that directory can go up to 500 kb and even 1 mb. However, again, in my Assets directory the largest is only 150 kb, and are a bunch of random gaming art pictures.
Just to make sure that the lock screen displays the wallpaper, I clicked lock, and the wallpaper is displayed. Is windows deleting the pictures too fast for me to notice, or have they changed the location of the large scenery lockscreen wallpapers?
EDIT: I'm running windows 10 pro, version 1803, build 17134.1 on a dell latitude. I downloaded and installed windows from the official iso just yesterday, oct 2018.
