The updated Start screen in Windows 8.1 can be customized in many ways with and without the help of third-party software. Even though Windows 8.1 doesn’t automatically add shortcuts of installed programs to the Start screen by default, you can pin your favourite programs and apps to the Start screen, add your own custom tiles with custom icons, set a tile size to small, medium, large or extra-large, set a custom picture as Start screen background image, set a video file as Start screen background, or you can even group tiles and then name those groups.
A lot of users who have already customized the Start screen by pinning and grouping tiles might want to change the transparency level of tiles and Start screen. As you should know by now, there is no option present under Start screen personalization to change the default opacity level of Start screen and tiles on the Start screen.
Users who would like to change the opacity level of Start screen and tiles on the Start screen have no option but to use a third-party tool named Start Screen Customizer.
