I've left the system files invisible at least since installing Windows 10, and it hasn't once been a problem. I can't remember if it was always this way, or if it's a recent addition, but there's a separate option for showing hidden files and folders. (With this ticked, system files remain hidden, so this one is a much easier tick to recommend, if you're technically-minded. You get to see %USERPROFILE%\AppData, which you'll probably want, but not stuff like hiberfil.sys and boot.ini, which you need much more rarely.)
