Further to post#2,
A really helpful thing to do (in general) is keep the installer exe files for programs you install, keep these installer exe files on a USB or cd/dvd disc... Then when you: change a computer to a new OS, wipe a computer to a fresh state, buy a new computer... you can just insert the USB/cd/dvd copy the installers from it onto the computer's harddrive and then run them to install the programs you want on the new machine. Note that this works well for offline installers (those which contain all their files and can work without need of an internet connection), it doesn't work so well for online installers (smaller exe files, because they don't carry the files they need, rather they download them from the relevant developer's website when you run these sort of installer exe files) unless the new machine is connected to the internet before you run the installers. This is a way of, at least somewhat, backing up your programs as well.
P.S. whatever you do make a system image first, so you can return to your old OS (your old OS in exactly the configuration you like it with the programs yu need installed rather than simply your old OS in factory default state) more easily if you don't like win10 or if something goes wrong during upgrade and you can't even get win10 to install.
