Click that option and you can then choose a slideshow with wallpaper. Windows 10 also has a Slideshow option included with previous versions. Select that to open a palette of solid colors that you can add to the desktop. One thing that’s new here is the Solid color setting. The window above includes a drop-down list at the top from which you can choose three wallpaper options. From there, select your desired Desktop background option from the dropdown menu or browse through your Pictures gallery. To do so in Windows 10, click Themes and Theme settings. Of course, you can always add alternative wallpaper to the desktop.
The extra folders are included at the bottom left of the Start menu. That opens the window below where you can choose to add more folders. In addition, you can also add more folders to the menu by selecting Choose which folders appear on Start. To add more tiles to the Start menu, switch the Show more tiles option to On. That includes a preview of the Start menu at the top with the selected settings.
Click Start on that window to open some further options.
