I can't unlock my laptop when i press cnrt+alt=del i typr administrator for username and it want unlock

RESTART THE SYSTEM >WHEN THE WELCOME SCREEN APPEARS PRESS ALT+CTRL+DEL ALL AT ONCE . NOW TYPE ADMINISTRATOR IN PLACE OF USERNAME AND HIT ENTER .

If you forgot your Windows password, you can create a Windows password reset disk to reset your lost or forgotten Windows password, i have created one with the tool Windows Password Breaker and reset my administrator password successfully.

If you are using windows xp......then only it will help..
there's a dialog box for entering password...
press ctrl + alt + del ------two times
another dialog box will appear
in the username box
enter "Administrator"
leave the password box blank...
press ok...
it will log into the default administrator account...

from here you can change or remove the password of other accounts and even delete the existing accounts

press ctrl+alt+del twice or 3 times and you will see a window where you can write your username... just write administrator and press enter (leave the password field blank)

if wour windows is xp when the password screen is apper press (ctrl+alt)+(del 2 times) u mast hold ctrl + alt and press del 2 times then the password screen well change antre in username : administrator py this way u create a new usear then go to usear accont and remove password from your assont i hop this work

As far as I know , there are two main methods to solve the windows password problem as follows:
1st Method:
Start system and when you see Windows Welcome screen / Login screen, press ctrl+alt+del keys twice and it'll show Classic Login box. Now type \Administrator\ (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows.
Now you can reset your account password from \Control Panel - User Accounts\.
Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.
2th Method:
Windows password reset software:
for example:Windows Password Reset. It is easy and convenient to use.

if you're running XP, you need to change the boot preferences to CD first, burn a CD with a particular linux kernel on it, specifically designed to blank an Administrator password. boot the CD, follow the prompts, change the password to a blank one, writing a new one in doesn't work because of MS security. after the kernel has done its work, restart. when you get to the login screen DON'T LOG IN JUST YET. press ctrl-alt-del twice should take you to the old username/password prompt. type in Administrator as user, nothing as password. bam, its yours. ^^

Try pressing ctrl alt del twice at the login screen and you should get a different login window where you can change the username. Change it to administrator and press enter without any password

On the logon screen press the crtl+alt+del twice till it will give you a window that ask for the username and password, erase the username(if there is) and type administrator no password and press enter. You should be able to logon to the administrator account. If your successful you can change the password of your previous account

press ctrl+alt+del 2 times and change the username to administrator and use blank password, and then goto control panel to change the password on your username.
