John's friend has a Windows computer from her deceased husband that she can't log into. It's used though. Leo says the best thing to do is start over if she doesn't want the data off it. Download the Windows 10 Media Creation Tool, save it to a thumb drive, and then plug it into the computer. Then boot to it, and reinstall Windows. It'll wipe the drive and give her a pristine version of Windows.
But if she wants the data, then she'll probably have to take it into a computer shop and pull the data off. She can pull the hard drive out and use a Universal hard drive adapter to connect it to the computer and she can get the data off that way as well.
