I am not a computer expert, I know little of it. I was given a desktop by my friend and it was using Windows 7 and had upgraded to Windows 10. Now I get this pop-up saying by 2020, Windows will no longer support security updates and all to my desktop. I don't know what to do. Can I reformat or erase everything on my desktop and just buy a Windows 10 Operating System without the need to have the disk that comes along with the computer when you bought it?
I mean the owner said when she first have the computer, when she turned it "On" she had to put a disk (Driver, she said) to make the computer work. She no longer have it, or she lost it since it has been a long time. I am sorry, I have limited knowledge about computers and I hope I can get help from here.
