What OS are you having?
Reset windows password as following instruction :

On XP you can try this:
Boot computer and press Ctrl+Alt+Delete twice when you See Windows welcome screen / login screen. It'll show classic login box. Now type "Administrator" (without quotes) in username field and leave password field blank, press Enter and you should be able to login Windows.
Now you can reset your account password from "Control Panel -> User Accounts".

On Win 7 or Vista:
Ctrl+Alt+Delete won't work, you have to use some windows password recovery software. I recommend Windows Password Reset .

To open your previous account you simply log in with the details you used when you left it.
This will automatically activate your account again :)

1.click start menu 2.click control panel 3.click user account 4.click the formal owner username 5. you will see various options one of which is change username, then click 6.enter your desired username and click ok

Hello pikeydad. I you don't have the owner's password I suggest you download something called Hiren's Boot here:http://www.hirensbootcd.net/download/Hirens.BootCD.10.4.zip
burn it on a CD and then boot from it and under Recovery Menu use the "Active Password Changer".
Once you remove the administrator's password (the owner's) logg in to the computer go to start-control panel- user accounts. You have to add you son's account and then log in under your's account. Then go back to start - control panel - user accounts and then click on the owner's account and click delete. You can delete the account only and keep the owner's files or delete the account and files completely.

if u r using window xp,

so just press ctrl+alt+delete(press delete 2 time) ur login screen change to black and its ask u username and password,just clean everything and in username type
"administrator" then press enter u r login in administrator.

now goto control panel then user account and delete ur old account password.logout and now open ur account

Give this a try.Enter wrong pass for more then 5 times,it ll ask u to enter the puk number....now call t mobile (150) and get the puk number...enter the puk number in the space given for pass....thats it...problem is fixed
if u had locked ur mobile then update the formware all saved passwords ll be deleted.

Go to:

https://www.google.com/accounts/Login

Log into the account you created. You should be now at the My Account page. You'll see a section called "My products". Next to that there's a little "Edit" link.

Click on that Edit link, and you should have an option to delete the account performanently.

go **** your self

Now do you get to your windows login screen or not? if you do press Alt, Ctrl and Delete at the same time and type 'Administrator' as the account and leave the password blank since this is the default password and press enter. If it does not work, contact previous owners or whoever you bought it from to obtain administrator password. Once you get in, you can change your old password to a new one which will solve your problem. It sounds like someone has changed your password on you so contact anyone who would even be a suspect in using your computer and question them as to why you can't login.

Hope This Helps
