Description :

If you are also a fan of the Windows Spotlight Wallpapers and don’t want to navigate to the *\Assets folder every time to copy and save the wallpapers, this is right script for you. The Powershell Script basically creates a folder named wallpapers on your desktop, copies the content of the *\Assets folder to your desktop and renames the file extensions as *.jpg because the file doesn’t have an extension in original.

The Script can be downloaded from the TechNet Script Repository too :
