In my experience, by the time you mess around and try to use other methods, a good 32GB thumb drive is probably the quickest way to do it (still not real quick, obviously).
Start w/ pictures and music and work your way towards applications.
Windows backup of your data files only and restore it on your new laptop.
You can’t move the applications, you’ll have to download and install the newest version for Windoze 8.1.
As for removing bloat ware, you’ll have to remove them from the add/remove control panel application individually.
Me, I use a Mac, so I’d just do a Time Machine restore and it would do it all.
