Microsoft recently released a new Windows 10 wallpaper package, titled Earth day, which includes a collection of ten different 4K Earth Day themes.
The Earth Day package is offered free to Windows 10 users, with ten high-resolution 4K themed photos, specifically for the 2019 Earth Day celebration, which was April 22.
The theme description reads: “On Earth Day 2019, marvel at the fragile beauty of threatened and endangered species and habitats from around the world – in stunning 4K resolution, a free exclusive set of 10 images for Windows 10 Themes. These images intended for use as surface wallpapers only work".
The collection can be installed by Microsoft Store just like any other application. To download go here.
Once downloaded and installed, the theme can be activated on any device of Windows 10 by going to the “Settings> Personalization> Themes” application. Just select the Earth Day theme and your desktop wallpaper should change automatically.
Like all other wallpaper based themes, you can switch from one background in the other by right-clicking on the desktop and choosing to go to the next or previous image.
If you want to install this wallpaper package / theme, you must run the Windows 10 update of April 2018 (1803 version) or October 2018 (1809 version).
