I think I read somewhere that Windows 8.1 was made to be able to be reset, and has the product key code built into it. I found the product key in the computer a while back, and still have it because I copied it down in case I needed it during a reset.
I read a lot and watched multiple youtube videos, and some people say you can just do a reset with no problem. And other people say there's a good chance the reinstall will fail because of missing files.
Would missing files be necessary to get on disk? Or could the computer just hook to the internet and find the necessary files by itself (I'm doubting that, but unsure)? If I need a disk before reset, where do I get it, and how much might it cost? Is it possible to just use a DVD-R and make it so if something goes wrong during the reset, I could always just revert back to what I have now?
It's for my son's laptop (HP). When he went to his aunt's house a while back her husband installed parental controls and an unknown number of other things onto his computer. Since then the computer has been having lots of problems. And they won't give me the password or help me to get rid of the stuff they put on his laptop. So I want to just copy his personal files to DVD-R, and then reset it so it's like it was when I bought it for him.
Any help/advice would be appreciated. Thanks.
