* * Purchasing Some Used HP's, 3rd Option Not Coming Up

I've just purchased 21 2 year old HP XP machines that were on a domain. I was going to get into them by choosing the 3rd option on the Windows sign in, (control, alt, delete), but it appear that has been disabled as the third box never comes up so I can select the particular PC name. I How can I get around this? Worse case scenario, I can take them back to that office, sign into the domain and delete the domain from there. That's a lot of hauling I prefer not to do. Thanks, Paul

Hello, You should be able to get the needed passwords from the person who sold you the machines. Since I have no way of knowing that the machines are not in a business office that you work for I can not help you get around a password to log on to the machine.
