How can I transfer everything from Windows 8 to Windows 10?

Episode 1423 (1:53:32)

Gary from Florida
Windows 10 Start Menu

Gary got Windows 10 and didn't like it, so he downgraded to Windows 8.1. If he buys another computer, can he use the image ID of Windows 8 on it? Leo says he really won't want to do that. Ultimately, he'll have to go to Windows 10 and it's pretty much the same, anyway. It sounds to Leo like Gary didn't have his Windows 10 machine properly set up and he couldn't find anything he needed. Microsoft used to have a free utility called Easy Transfer Wizard, but they've killed it and now he would have to buy one from Laplink. EaseUS has a free one called Todo PCTrans Free. Leo says EaseUS is a good company and it will probably do the trick.
