If you’re looking to change up the look of your Windows 8.1 computer, one of the easiest things you can do is change the theme. This includes changing the background on both your Start screen and your desktop, as well as altering the colors of your Start screen. Here’s how to do it:
1. Start by going to the top right-hand corner of your screen and clicking on the search button. In Windows 8.1, you can also open up the charms menu and click on the search button there.
2. Once you’ve opened up the search menu, type in the word “background” and you should see a selection of options appear.
3. Click on “Change the background and colors on the start” to change the background on your Start screen. Click on the picture you want to use, and it will be added to your Start screen.
4. To change the background on your desktop, type in “background” again and click on “Change desktop background.” Select a different picture for your desktop and click “Save Changes.”
5. To change the colors on your Start screen, type in “background” once more and click on “Change the background colors on start.” Choose any of the default screen colors, and you can also change the color of the background itself.
6. Another way to change the background on your desktop is by right-clicking on the desktop and selecting “Personalize.” From there, you can click on “Background” and choose a different picture.
And that’s it! With just a few clicks, you can completely change the look of your Windows 8.1 computer.
