Troubleshooting
• The password reset disk cannot be used to reset the password on another computer.

The password reset disk that you create can only be used with the computer it was created on. For example, if you have two Windows XP-based computers that have the same user names and passwords, a password reset disk that you create on the first computer cannot be used to reset the password on the second computer.
• The password reset disk contains sensitive information.

Other users may be able to use the password reset disk to gain access to your computer. For this reason, store this disk in a safe and secure location.

Nifty little thing you have dug up there LD.
I'll make one for sure, never know when it may be handy. Sudden amnesia or just from getting old

Glad I am still using floppy

There are infections that when removed from the pc it's possible it has changed your password and you're not able to login.

Hmm, nasty fella. I see your point. Just to bad so few are using floppy nowadays.

But a very nice little tool for those who have.

there is a "NTFS Password crack" utility out there that not only allows you to reset the password for any account, it also allows you to re-enable deactivated local accounts and even create them. that is what I normally use when troubleshooting an issue with a computer. But this is a great find none-the-less.

I like this.

my laptop doesnt have a floppy drive. can I use a USB stick instead, and use it with vista?
