For Windows 10 users, Microsoft today released a new theme wallpaper package through the Microsoft Store. The theme package is called “Colorful Boats PREMIUM” and contains 14 high-quality 4K wallpapers. The app describes it as follows: “These 14 bright and gorgeous boat images can act as Windows 10 wallpapers for free. These high-quality 4k images are only used as desktop wallpapers”.
Once you’ve downloaded the wallpaper pack, go to Start, Settings, Personalize, and Themes, and then click the theme you want. To apply based on the current wallpaper and change to the most appropriate color, go to Custom, Color, auto-select the original color from the background.
