In order to change a user’s password on a Microsoft Windows operating system, log into any account with administrator privileges and navigate to the control panel.
There, click on User accounts and then on Manage another account.
In this case there’s only one user – Administrator, so we’ll be working with in. If there would be multiple users, you could choose whichever you need. Click on the user you’re going to change the password for and then click Change the password.
Finally, enter the user’s current password and then twice the new password and you’re done.
