Personally,
To cut thru millions of wrong answers, this is what I did and still do.
- Download Boot Hirens USB
- Get a Blank USB
- Download Rufus
- Install BootHirens USB as a Bootable USB using RUFUS
- The Key combination varies per Laptop or Desktop, but change the Boot setting to Boot from USB
- Hirems will load to a desktop
- Hit the Start Button (Windows Icon Bottom left
- In the list of Utilities, locate Windows PW reset
- Open it. You will see all of the user names. I leave the Password Blank & Save. (Local Accounts Not Domain Accounts)
- Remove Hirens Boot USB
- Boot into normal mode>Use the local acct you just updated the PW or left blank and saved
- Enjoy your laptop (All free), and there are many other utilities. Hirens is a lifesaver
