Turn off Windows 7 Password Protection
To turn off password protection for Windows 7 account, make sure you are set up as an administrator on your computer. Then, begin by clicking on Start and then open up the Control Panel.
In the Windows 7 Control Panel, click the User Accounts and Family Safety option.
Under the User Accounts section, click on Change Your Windows Password.
In the Make Changes to Your User Account window, click on Remove Your Password.
Here, Windows 7 asks you to confirm your choice to remove your password by typing in your current password. This step is critical because it prevents just anyone from hijacking your account by removing or resetting the password. After you have typed in your current password, click the Remove Password button.
Windows 7 then takes you back to the Make Changes to Your User Account window. Unfortunately, Windows does nothing to confirm that you have indeed removed your password other than the new option on this window titled Create a Password for Your Account.
