Password Lost!!

[Guest]

I am using Windows Vista Ultimate on an Intel Core 2 Duo notebook. I am the
only administrator on the computer and I keep a password.

I had left my notebook on Sleep mode for two days and the shut it down.
After sixteen days, now when I opened the notebook, it asked for the password
as usual, but I couldn't remember the password.

I do not know how to login as a Guest user.

I have created System Recovery discs just in case, but I haven't made any
Password Reset Disc.

I looked up Microsoft Technical Support but unfortunately, I came to know
that there is no way to recover an Administrator Account password without a
Password Reset Disc.

PLEASE LET ME KNOW THE SOLUTION TO THIS PROBLEM!!!

PS: Can I use a password reset disc made on another Windows Vista Ultimate PC?
