Windows 10 is generally not free if you need to reload it after a hard drive failure unless you have a valid license for it. If your laptop originally came with Windows 10, you should be able to reinstall it using the recovery media or the recovery partition that came with your device. If you do not have a recovery option, you may need to purchase a new license.
Regarding the utility to remove a password from your new hard drive, there are various tools available depending on the type of encryption or password protection you are dealing with. If the drive is encrypted with BitLocker, you would need the recovery key or password to unlock it. If you're looking to remove a password from a non-encrypted drive, you can typically do this through the drive's properties in Windows or using third-party software designed for drive management. However, specific utilities and methods may vary based on your exact requirements and the type of password protection in place.
