How do I enable blur behind Windows 10?

As a keen Windows 10 user, I'm curious to know how I can enable the blur effect behind my windows. It's a visually appealing feature that I've seen on other systems and I'm wondering if it's possible to replicate it on my own machine. Could you please guide me through the steps to enable this blur effect? I've searched online for solutions but haven't found any clear directions that work for me. I'm hoping you can provide a detailed and straightforward explanation to help me achieve this desired visual enhancement.
