This happened to me last week as well. I assume that this shit came with any of the recent updates.

It really infuriated me, especially the usage of the word "need" and the fact that the dialog doesn't offer an option like "no, and don't bug me with this ever again". Fortunately, after hitting the "remind me in 3 days" button, I looked a bit and found an option that does make it go away forever.

My Windows is in Spanish, so I don't know the exact name of the configuration settings in English, but you can find it in the Win+I configuration dialog. Look for "notifications and actions" (or something very similar), and there, look for a checkbox whose text reads something like "suggest ways to finish device configuration to get the most out of Windows". In fact there are six checkboxes in that screen and every single one looks like an annoyance, so I disabled them all.

At least you didn't get a "Windows needs to restart and update" in the middle of a presentation ...

Windows forces some kind of setup flow with major updates now it seems.
