Windows 10: What is this blue box?

If someone can tell me what this blue box is, that would be much appreciated.

So apparently, on all my Windows devices, I have had this blue box. Whenever I click on it and press Enter, it shows my desktop icons. I have searched it up before and could not find any answers.

Hello,

For better assistance, we need the answer to the following questions:

• Does the blue background applies on all the links on the search results page?
• Does this issue happens only with Internet Explorer?
• What are the steps you have taken to troubleshoot the issue?

We are looking forward to your response.
