How can i reset my password when i dont even know the password to login

dont have access to your personal accounts and if you dont know we definitely dont know

If u dont know ur router login password then reset it but keep in mind it would reset to default.
And if u lost ur wep or wpa2psk password then just login from a computer or directly via web to ur router 192.168.0.1

if you know your old password, login to router and go to administrtion or maintanane (normally comming administration option) and you can see there is an option to change password.
if yo dont know your password, you need to reset your router manually by pressing reset button on router (check back or sides) by doing this process you need to reconfigure internet connection and wifi settings, so before you done you should keep internet connection details (username and password by internet provider) and wifi settings.

Hope this helpfull.

Use windows password reset tool is the best way to reset windows password.
Here are three tools for you.
Windows Password Reset( http://www.windowspasswordreset.net )
Windows Password Recovery Tool ( http://www.windowspasswordsrecovery.com )
Windows Password Crack( http://www.windowspasswordcracker.com )

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 .

You can only reset the window login password, if you have created the password reset disc when you created that password. If not, then the only solution is to do the recovery.

You can request a password reset by clicking the Forgot your password. link located near the "Login" button on the log in page. We will then send you an email with a link to reset your password. Please make sure your e-mail is correct.

Hi,

You can login into your computer by "Safe mode with command prompt" option and use "net user" command to reset lost windows password. Or you can use third party password recovery software
