How to Get Rid of a Password on Your Computerby Michael Butler
If you have password-protected your Windows computer, you need to enter the password every time that you start the computer. A password helps protect your computer from thieves and unauthorized access. However, if no else uses your computer and you think it is safe from other people accessing it, you can remove the password and the need to enter it every time you start the computer.
Click the Windows "Start" button.
Click "Control Panel" and "User Accounts."
Click "Remove Password."
Enter your password and click "OK." The next time you start your computer, you will not need to enter a password.
