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. J'ai essayé booting from a USB but it wants to reinstall windows and he doesn't really want to lose his files. J'ai essayé typing this into DOS that J'ai trouvé on another site:
```
Net user administrator /active:yes
Net user administrator p@ssw0rD
```
But J'ain't got anywhere, please can someone help?
## Mise à jour
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.

## They talked him into doing things on his laptop
-
**Please disconnect this PC from the internet tout de suite**.
- If your uncle has used the PC for intenet banking then his bank account details may already be compromised.
-
**Let his bank know what has happened immediately**.
-
They will be able to advise him how to change his internet banking details over the phone.
-
The talktalk scammers have already conned some individuals out of thousands of pounds.
-
**Change all his passwords (email, websites, etc)**
- Do this from another computer you know is clean.
-
**Then get professional advice on how to fix this.**
-
You don't know exactly what trojans or whatever nasties have been left behind on this PC.
-
Getting the password back is only the first step of a cleanup and **the safest thing to do is to reinstall Windows**.
-
A professional IT support person should be able to get any personal files saved first (in a safe way) before Windows is reinstalled.
-
**But I really want to clean up this mess myself!**
If you feel you have the technical skills to fix this then:

As per comment by [JamesRyan](https://superuser.com/users/4236/jamesryan) consider giving your uncle user access rights only (standard compte utilisateur). Si vous êtes willing to support him in the future keep the Admin rights to yourself. That will au moins limit the damages if it happens again.
