There is no reason to say you will lose what is stored in your hard
drive just because you don’t remember a password (except if data is
encrypted and the encryption password is the one lost, which I don’t

if this is happening in a corporate environment, then your IT department has most likely a way to reset your password.
panic. Just ask them to reset your password. If they refuse to do it,
put your boss on notice, so they can take appropriate action.
