Windows 10: What does this box mean & why can't I download Apps?

I can't download any programs, or think they're called Apps now. I only bought my brand new laptop recently and nobody else has used it. It has Windows 10 Home.
I'm trying to download HP printer software and I also tried other apps such as Google Earth.
Everything else is working on it, but when I try to download apps, a box appears that says: Do you want to allow this app to make changes to your device?
Then on the same box it says, to continue enter admin user name and password, but nowhere to put an admin name and password. Then it only gives me a No button option to click on, so then the App doesn't work.




I looked at account setting and it says my account was logged in as a Local Account, so I changed it to being logged in with Microsoft as my Outlook name and password, but the same happens.
I right clicked on the App exe and clicked on Run as Administrator, but it's still the same.
I've gone all through the Account settings but can't see how to change my account to something else, or if I'm not logged in as admin, but as far as I know I only have one account set up anyway.
This is so frustrating. All I want to do is set up a printer to write some letters.
Any help will be appreciated.

2N? What does this mean?

I've been seeing this a lot lately with DDR3... they'll list the timings, something like 7-8-7-24-2N. What does the 2N mean? I assume it means the same thing as T (command rate), but I don't know for sure.

 

Why can't I download the new PC programme?

And your suggested second step........ well I past to my Outlook.com log in but when I clicked on the download button I was sent to a page which said:

I wonder if there are too many things being changed at the same time resulting is mistakes being made?
