I bought a laptop today. Windows
(Medion akoya s17405)
I'm 20 years old.
When I first set it up, I accidentally forgot to confirm that I was over 16 years old.
Unfortunately, I don't know where I can confirm this in retrospect.
Can someone please explain it to me?
I have no idea where you confirmed your age or not. As long as it is not necessary, I would leave it. Apparently it was not required that you had to be of legal age, otherwise you would not have gotten around to confirm your age.
