so you set your laptop back to factory default?
yes, all is lost.
do you have any restore points in windows left?
I'm restored it got it back but can't sign in again
Do you not have your old password?
There is a bug that can get you administrator privileges on Windows 7 that involves startup repair, but it won't work for windows 8/10.
Alternatively you can just install a crack onto a USB.
