I have been donated a HP Envy M6 laptop to use with a charity group I am associated with.   As it had been well used over the years and was full of apps and all sorts of stuff and consequently running very slow.

I decided to clean it up back to factory settings.  Following instructions this process appeared to go very well right thru' to Windows reloading (all taking close on 2 hours).

However it now will not accept the original password to access the computer given to us by the previous owner.   This worked fine before the reset.  Consequently we are locked out and I am not able to contact the previous owner.

HELP  !!!
