It could be from the Dell Update previously. It did an update, but I don't know what it was. Then Microsoft has downloaded umpteen updates. So I am not sure. I have done no graphics driver update on my own, with this computer. On my older computer, yes I had to after the horrific upgrade to 8.1. (from Win8)
I got this computer in early January. So it is possible it was updated before they sent it out. I have had other things going on, and have not compared what I have to what Dell is showing for drivers that I could update the driver with. I did try to update a card reader driver, but Win10 would not allow that. It said what I had was better. (paraphrase) I feel sure that was from Win Updates. It is a great idea to let Win Updates show me what drivers I could update to. Then I can check it out, and see if I want it. It is a very bad idea to automatically install one. It may be glitchy. If you were in the middle with something, the last thing you need is to drop that, and have to work on computer "issues".
