Please, please tell me that there's a way to undo this terrible mistake. My needs for the computer are simple. I use a desktop computer. I do not, and will not, fool with "social media", "games", Skype, etc.; E-mail and Google are all I'll ever need. I despise touchscreen technology. I'm in my sixties and never really wanted to get involved with computers at all. Whatever whistles and bells Windows 10 offers mean nothing to me (I hated leaving XP), and I want my stuff back!
Can I use System Restore, or some such, to recover what I've lost, or is there no way to go home again?
