Creating and sharing Windows 8 themes without using any software
All you have to do is prepare the background you want and download it from the internet so that you can use it to create your own theme, or you can use your own image if you want, but make sure that the background image is of high quality and large size. Then right-click on the desktop and choose Personalise to start creating the theme. Now below and as you can see in the following image Desktop background, Color, Sound, Screensaver, and through these options, you will create your theme.
First, click on Desktop background and click Browse and choose backgrounds from your device, where you select all the backgrounds you want to be in the new theme to appear in a sequential and alternating manner on your device and change. You can also choose one background if you want. Then click Save Changes.
Then write a name for the theme and click Save to save the theme on your device. Now you can share the theme with your friends on social media sites or by exchanging flash drives or via email. Any Windows 8 user can easily install it on their device by simply clicking on it. A wonderful and distinctive method, and the themes you create will be like official Windows 8 themes and will also be light on the device and will not cause slowness. A unique method that I recommend trying.
