Hi @matjung
Here is some more information on Microsoft User Research:
We want you to influence the next wave of Microsoft products. Your involvement will make products easier to use and help shape future technology.

It most likely wants to read your profile such as your name to track participation to your user profile. There is a button on your photo that states Show details. That may have given you a further explanation of what exactly is being read, but I have not seen this before.
It is great that you are asking questions and user awareness is good as well. That is why Microsoft made these types of screens, which gives the user the ability to have the ability to decide whether to continue or not.
