Someday I have got a call from a friend who had managed to forgot his administrator password to his Windows XP computer. I told him don’t worry, it is almost impossible to access the computer as it happens to the best of us.
This method is easy enough for newbies to follow- it doesn’t require using any complicated commands. And it just call you a little money- I mention that because you may find some free one, but in fact all these software are not security or no use at all.
This site provides a tool to recover lost Windows XP passwords. It works for administrator and user accounts. It works with encrypted files and password hashes. It even works if no passwords at all are known for the machine (as long as you have another computer with internet access to view this website with). Author claims it also works with Windows NT and Windows Server 2003 and Windows Longhorn, but the BEST thing about it is the fact that it can reset your passwords, but simply reveal them for you to remember and then use. Give it a try. The author would like to receive feedback. The fee for the service is very cheap, and is really just to cover server costs.
if you can’t find it helpful. Here is another simple way to access Windows XP with Administrator rights and privileges if you have password protected your User account on your Windows XP system and can’t remember the password(s) to login. Whenever Windows XP is installed on a system, it creates a default account called "Administrator" and by default this account is not password protected. Therefore, if you bought a brand name computer (such as Dell, HP, Compaq or Sony)or you have installed Windows XP yourself. You should be able to login to the computer through the unprotected Administrator account.
