Got a lptoptop in today from a scammed old lady. Managed to get £1000 from her credit card and also locked her out of Windows 7 with a syskey password. Never had a ransomeware like this before.
Thought i'd be able to restore to an earlier date but the scammers also removed all restore points.
Going to try NT offline password manager next as i've read it may be able to do syskey passwords as well as windows passwords.
