This is a bit long winded, but it is a simple process.
The only way you can do this, if you did not create a password reset disk
when you created the password, is to remove the password for your account
when logged in with another administrator account.
The easiest way to do this is to temporarily enable the Built-in
Administrator account and remove the password on your administrator account.
Follow these steps.
Go to Start and type: cmd.exe In the Results, right click the Cmd.exe
program and select the Run As Administrator option.
In the command window, copy / paste the following command:
net user administrator /active:yes
Press Enter. You should see a message that the command was successful. This
will place the built-in administrator account on the login screen.
Next, go to Start and click the arrow to the right of the lock computer
button. In that menu, click Switch User. When the login screen appears click
the built-in Administrator account and log on.
Go to Control Panel / User Accounts. Select Manage Another Account. Select
your administrator account and then click the Remove Password option. Click
the Remove Password button.
Now go back to the same boot menu and this time select the Log Off item. On
the login screen, select your administrator account.
Once you are logged on, use the same steps to open the administrator command
prompt and use the same command, only this time change the "yes" to "no".
This will hide the built-in administrator account again.
Open Control Panel / User Accounts, select your administrator account and
create a new password. This time, create a Password Reset Disk that you can
use if you ever forget your password again.
