I might need to go to sleep, sadly
So I might have to continue tomorrow. I will receive any messages you post here, so don't worry about that.
To make a screenshot, if you have a full sized keyboard there should be a button somewhere above the arrow keys that says "Print Screen" or some abbreviation of that. Pressing the button saves your screen as an image, and then you can paste it into any program to save it. I'd use Paint and just save it as a JPEG file.
Be careful of what else is visible in the image, though; we do not want you accidentally getting personal information in your screenshot that you will post online. If possible, you can use Paint to crop out the Device Manager window, since that is all we need.
I'm still trying to figure out the easiest way to post a picture on this forum, though
I've never needed to, so I'm not entirely sure how to do it. I'll keep looking while you get the screenshot
