Windows Entry Experience: File

Hello, I just noticed that a file named "Windows Entry Experience" appeared in my downloads folder, but I haven't downloaded anything. I would like to know what it is doing there and why. Its contents, by the way, deleted themselves, and I only have an old screenshot of the folder: https://zupimages.net/viewer.php?id=22%2F16%2F515z.png
