We can't ignore the past here. That is, no PC user goes without backups of what they can't lose so the best way is to take your backup to the new machine and test if you can restore the files and such.
Apps are usually restored first.
If you never did backup, now you have to find where your stuff is and then copy it to what you have such as USB drives or such and then take those to the new computer and copy it to where you like.
Some things like Web Browser settings are moved over with the browser's SYNC feature.
