I have no idea what you and the Microsoft people are talking about? I'm really that computer illiterate. Especially with PC's. I've alway owned Mac's. This is my first and will be my last PC, that I'll ever own. If somebody out there, could please explain it to me, in laymen's terms, on how to properly download Windows 10. Back on this acer laptop, I'd really appreciate it. My sisters Acer laptop, I found out last night from her. Has been updated to XP, by her husband. That doesn't help me very much at all. Everything on the computer, has been removed by Microsoft yesterday, on this Acer laptop by the Microsoft people. So now, it a blank slate and all I need to do, is to reinstall Windows 10. So that I can get my new codes from Microsoft and become the new administrator of the Acer laptop. Then I can download my Dealertool apps. Otherwise, I'm going to have to take it, into the shop and have it done, and that's going to cost me money, that I really don't have to spend. I don't need a licence. I just need the Windows 10 app. To re-download and that's all that I need to do. I don't need anything else. Because, to download, The Dealertool drivers and to make the Acer work properly? I need to be the administrator and have the codes. So that Microsoft will let me download my this post I screwd it up apps. I bought the Acer laptop on eBay, from a church action. It was a student learning computer from a school. . What I need to do, is to just re-download Window's 10 and that's all. The Windows people had me run the computer in a mode that deleted everything on it, including the old Windows 10. Because, I was not the administrator and I need to be, to get this thing up and running like it should be. So that I can download everything, for my Dealerstool, so that it will work. I'd really appreciate the help.
