ANYONE KNOWS HW TO LOGIN TO WINDOWS XP WITHOUT A PASSWORD (BY PASSING THE PASSWORD OPTION)

how can i get to know how?

U do this
Go the run command, type control userpasswords2,
Click on the user account you wanna use, enter the password if, any and uncheck Users must enter username and password to use this computer.

there would have been any better help than your, thanks alot. am very grateful. but this pocess will only work if you have access to th computer already. wht if it were a blank system. actually my elder sister said she's forgotten her password and wants d engineer at home to do it without avin to format the PC

I post 2morrow
Cheers

Also wanna know the condition, OK.

Just go through safe mode with networking and after loggin in change the password in control panel to whatever you want

Why not for Vista? Abi u scared of vista?

THE PASSWORD YOU ARE TALKING ABBOUNT IS KNOW AS THE POWER ON PASSWORD IF YOU ARE NOT AN EXPERIENCED ENGINEER YOU WILL NOT BE ABLE TO THIS BUT I WILL EXPLAIN THE PROCESS BELOW:

FIRST YOU WILL NEED TO OPEN THE SYSTEM AND REMOVE THE C-MOS BATTERY.THE C-MOS STORES DATA PERMANENTLY ON THE SYSTEM OTHERWISE KNOWN AS THE ROM.
AFTER REMOVING THE C-MOS BATTERY,THEN YOU CHANGE THE JUMPER OF THE C-MOS BATTERY,POWER ON YOUR SYSTEM AND GO TO TO C-MOS SET UP TO CLEAR THE PASSWORD,AFTER WHICH YOU SHUT DOWN,PUT THE BATTERY BACK IN PLACE AND CHANGE THE JUMPER SETTINGS BACK TO WHERE IT WAS BEFORE AND POWER ON THE SYSTEM AGAIN.
NOTE IN SOME MOTHERBOARD,THE C-MOS BATTERY MAY NOT HAVE JUMPER SO WHAT YOU NEED TO DO IN THIS CASE IS JUST REMOVE THE C-MOS BATTERY,GO TO YOUR C-MOS SETUP AND CLEAR THE PASSWORD,SHUT DOWN,PUT THE BATTERY BACK AND POWER ON YOUY SYSTEM,THE PASSWORD WOULD HAVE GONE.
CHEERS.

Brova !
