Windows 10: Windows 11 Desktop Rounded Corner

Hello, I'm wondering if someone can help me with Windows 11 and its rounded corner desktop. I was at Best Buy this evening and their were two Microsoft Laptops running Windows 11: one was the Microsoft Surface Go and the other was the new Microsoft Surface Laptop Studio. In both, when the Windows 11 Desktop was displayed with no applications running, I noticed the upper corners of the desktop were rounded and curved and matched the curve of the laptop displays themselves. It looked stunning and gorgeous. I have an older Microsoft Surface Pro 7 with Windows 11 running but my desktop corners

:)

 

How to bring back round window corners on Windows 10?

I like the look of Windows XP, and Windows 7, and like the round corners of the windows of the apps. Windows 10 seems to take a step to remove them and make it 90 degree corners.

Are there ways to bring back the round corners on Windows 10?

 

Round corners

I tried to make my window corners look rounded (by enabling immersive search in registry editor) but the changes didn't appear, and my windows version is 1909.

Any help please?

I tried that site a few days age, my computer has been cleaned by Windows Defender, the first to report that I was infected with Malware, also by Malwarebites, Spy Bot , and a few more that monitor my computer, thanks for trying, but beware.
