Do you have multiple printers? Don't let Windows manage your default printer. (Settings > Devices > Printers and Scanners - uncheck "Let Windows manage your default printer") especially helpful if you have a normal printer and a specialty printer hooked up to the same machine. I can't think of anything else specific that I have done to any Windows 10 computers offhand but if you have a specific thing that's bothering you I may know where the off switch is. So far I am fortunate in that all of my win 10 experience is mostly with "use this for browsing the internets" but we are getting ready to switch over all of our work computers so I am going to be learning how to answer all these questions soon (mostly for myself, as technically, we have an IT department, but honestly I think I know as much as they do in some respects and in others I probably know more.
