Generally, when you change local account password in Windows 10, you will be asked for the current (or old) password. You have to type the current password before you can set up a new password.

2) Start or restart the computer, and access its UEFI BIOS setup. Set the USB device as the first boot device and press F10 to save the changes. This will force the computer to boot from the USB drive.

Step 3: Change Windows 10 password.

1) After the "Windows Password Refixer" screen appears, select the Windows 10, select the account whose password you need to change, and then click the "Reset Password" button.

2) Click "Yes" to confirm that you want to change the password, so the user's password will be changed to blank.

3) Click the "Reboot", click "Yes" to confirm that you want to restart the computer and quickly disconnect the USB flash drive.
