Can I reinstall Windows on a used computer?

Episode 1456 (24:13)

Jim from Riverside, CA
Windows 10

Jim called to ask about how he can reinstall Windows 10 on a computer that's been given him if the person who bought it owned the software. Leo says that was the old way of thinking. The new way of thinking is that Windows 10 is licensed to the computer, and not the owner. So if he was given a Windows machine that runs Windows 10, and needs to format and reinstall Windows, it will activate.
