The following will discuss some ways that you can use, if one day you forget the password to login into Windows XP Operating System
1. First way (Most Easy)
All you have to do is just go into Safe Mode Windows XP, the way is by pressing the F8 key continuously (so as not to miss) when booting before getting into Windows XP, if you have selected safe mode, then the time will come Windows XP, will there Login process as usual, by default will have an administrator user account, just choose the administrator user account, if not in the password then you can easily get into Windows XP, but if it turns out that administrator user account already dipassword, and you do not know your password her, then you can perform the following Both Ways
2. Second mode (Half Easy)
How this is done if it turns out the user with a password protected administrator account, and you do not know what the password. In this way the basic concept is to remove the password from the user's administrator account (or any other user account), we will use tools tool called ERD Commander 2007 (51.49 MB) (latest news maker this software has been acquired by Microsoft, but you still get this software in some particular place :-)). To use this application, you need to burn it onto a CD first, to then be used as a boot CD, and the process removes the password on the user's particular account. Actually there is one more way, that's worth a try too, that following the Third mode.

3. Third mode (Somewhat Easy and recommended)
In this way, we also uses the tools of the Free Software Open Source application called Ophcrack as a tool. It is better to use a LiveCD version to make it more easily. The workings of this application, is going to show all the passwords of every user account in Windows XP. To use this application, after successfully download the file iso (451.72 MB), you also need to burn it onto a CD first, then use it as a CD boot (also called LiveCD). If Ophcrack boot process is successful, then presto, all passwords will appear scattered on screen, this third way might require patience :-).
