Now that you've installed Windows 10 and mastered the basics of Microsoft's new operating system, you're going to want to start digging deeper into some of the customisation options available — like automatically changing the system interface colours whenever you pick a new wallpaper image.
Windows has a long and proud history of letting you tweak the interface to get it just the way you like it, but with this Windows 10 feature you can just change the desktop background to get a completely new look. The configuration page you need can be found in the Personalisation section of the Settings app.
Choose Colours and then toggle the Automatically pick an accent colour from my background switch to on — you probably also want to enable the Show colour on Start, taskbar and action center option too. Head to the Background page and switch between a few different backgrounds to see the feature in action.
Now you can get a fresh look for your operating system even if you hardly ever see the desktop itself. It's also worth mentioning Windows themes here: If you've never come across them before, they're packs of customisation settings that include wallpapers, colours and even system sounds.
If you click on Themes then Theme settings you can see your current theme, create new ones and download some professional-looking alternatives straight from the Microsoft website (click Get more themes online). Remember you can sync all of these settings between all of your Windows 10 devices via the Accounts page in the Settings app.
