There are programs on the Internet that can reset the password on a windows machine. If you do a google search you can find some without much trouble. I found one that makes a bootable CD and then you can reset the password like that. Alternately, if you are an administrator, you can reset the password for a user using computer management and clicking on users and groups. As to your second question, I can’t understand what you’re saying; your English is not very good.
