One of the problems with a virgin install vice upgrading is you have to install all those apps, and what about those modern UI apps and their data??

I got a utility called 'window 8 app data backup' or something very close to that title. I backed up the data app data for all the installed apps on my main box and then used the same software to restore it to my W10.

I won't install all my apps from my main box, just the ones I'm most interested in. The app data backup is smart enough to only restore the data for programs that actually exist.

The software is free and simple to use and well worth getting IMO.
