It doesn't work smoothly in all cases, though. My existing local account persisted after upgrading in-place from Windows 7 to Windows 10, but not all of my apps worked afterward. The Sims 3, for example, would no longer run on my local account. I had to start using the Live account and reinstall some apps as that user to get them to work again.
