Cryptography Question:

Answer #1
Forgot XP Password
The other day I got a call from a friend who had managed to
remember his administrator password to his Windows XP
computer.

My heart sank as I told him it is almost impossible to
access hi PC now as this was the only account on the
machine, and with no password Windows XP was not going to
let him in!

Forgotten XP Password...

As I stared at my mates computer and asked if he had ever
made a Password Reset Disc I already knew what he was going
to say...

This situation reminded me of asking many friends for their
latest data backup CD/DVD when their computer crashed and
need a rebuild - they NEVER have one!!!

...well a quick check on Google and I found a great service
that could just help my mate out.

This site provides a tool to recover lost Windows XP
passwords - YEAH!

It works very prefect to regain your password .Also use to
bootable CD/DVD or usb

There is a free service as well as a priority service that
will retrieve your passwords within minutes. The fee for
the priority service is very cheap, and is really just to
cover server costs.

Answer #2
Actually, if a person has a Windows XP CD - he can reset the Administrator's password and from there gain access to the OS. To do this: insert the XP CD and act like you're going to reinstall XP. Don't repartition anything - that would destroy your data forever! When it gets to the screen where it says it is "loading devices" - hit F10. That will drop you to a command shell where you can re-set the Admin password. After that is done - cancel the "Install".
