If you're getting slightly bored with the way that your Windows 10 installation looks, check out the large collection of free themes that Microsoft is currently offering for download.

A theme is a collection of desktop images, colour schemes and sounds to make your computer feel, well, a bit different to normal. And you can choose from categories including movies, art, animals and more. And while some are a little too garish, such as the one shown in the screen shot here, many of them are very pleasant indeed.

You'll find them all at https://support.microsoft.com/en-us/help/13768/desktop-themes-featured and they're free to download. Once downloaded, just click the "Open" button that should appear in your browser, to install them.
