Hi, I just sold a old laptop with windows 2000 professional as the O/S. While trying to remove all folders i removed the user name which i used so now when windows starts its prompts for username/password but i have none and it won't let you click cancel or ok without entering correct u/n & p/w. Is there some sort of default username/password for administrator or some way to get into windows...please help i need to post this item tomorrow !!! Thanks.

There's various softwares on the web which will change/crack passwords, so I suggest you do a search on google. Or just reinstall the OS with a nice clean OS
