To know where are saved all the wallpapers and the screen lock are used by Windows
Sometimes we see the background image of a theme, or a screenshot of the block and there is the desire to want to save. The backgrounds of the themes of Windows 10 and the screenshots of the block, in fact, are real shots performed by professionals in the particular conditions of light.
The question that we do when we meet one is: where is the file?
Default wallpapers
The themes of the wallpapers are in this position
%SystemRoot%\Web\
just copy the path in the address bar of File Explorer to navigate to the location to save the wallpapers
Themes
The backgrounds of the installed themes are saved in another location, for the accuracy two
%AppData%\Microsoft\Windows\Themes\CachedFiles\ %AppData%\Microsoft\Windows\Themes\TranscodedWallpaper\
Lock screen
The themes of the screens block, instead, are saved in this location
%AppData%\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets
You need to make a clarification.
The files of the backgrounds images are real, but they are not always saved with the extension. To use them, or only view it, you need to after you have copied the image file, add the extension .jpg to the end of the name.
