lost windows xp administrator password

[ma2jun]

Hello,
My query is regarding my operating system,
I installed windows XP prof. some time back in my pc,
I became the administrator, and made another user in it,
The problem is, I forgot the password of my administrator account,
I did not make a password recovery set in it,
neither did I place a hint in the passsword,
Now, this account contains many important documents,
Is there any way in which I could recover either the lost documents or the password?
I cannot afford to uninstall or format my disc,
If anybody can help me out of this,it would be great,
Also I only had a single account in the administrator group,
the other accounts are on "limited features"
Thanks,

楼主，你写了这么多，我看了半天才看懂一点，建议下次问问题最好用母语，不然很多高手会连看都不看的
你的问题就是忘记了密码吗，有点麻烦。你用其他的用户名登陆呢？

看那么英语是挺麻烦的。

你可以使用ntfs for windows/dos进入到ntfs分区里，然后定位到winnt\system32\config目录，删除里面的sam文件，再进入xp。
