My Uncle got a phone call from hackers pretending to be TalkTalk and as he is elderly and was tired, they talked him into doing things on his laptop. When they started to talk about banking etc he twigged and hung up but they have put a password on his laptop which we can't get past.
He originally had Windows 7, but had upgraded to Windows 10, but it is a local password that has been added. I've tried booting from a USB but it wants to reinstall windows and he doesn't really want to lose his files. I've tried typing this into DOS that I found on another site:
Net user administrator /active:yes
Net user administrator p@ssw0rD
But I haven't got anywhere, please can someone help?
Update
Thanks for all your help. Used Ubuntu and chntpw and managed to remove password. Nothing seems untoward, no software installed and malware bytes found no threats. I guess my uncle cut them off before they did any of that.
