However, changing the Start screen isn’t a process that’s necessarily as straight-forward as it can be. That’s what we’re here for: to make things easier on you!
With this guide, we’ll show you how easy it is to change the background on the Start screen. Most of you may not like poking around in there, but at least you can customize it to your liking so that it’s more pleasing to your eyes whenever you do dive into Metro.
How to change the background in the Windows 8 and 8.1 Start screen
Head over to the Start Screen, if you aren’t there already. If you’re at the classic desktop UI, just press the Windows key on your keyboard, which should take you straight there.
From there, type in “change start.” Click on “Change the background and colors on Start,” which should be the first result that comes up.
Now, a “Personalize” menu will come up in the Metro UI. Here, you can pick from a multitude of images that you can slather the Start screen with. Once you pick one, you can also tweak that image’s by messing with the “Background color” and “Accent color” settings.
