It's been a while since I've touched windows, but I think it has a similar system (although the option to run was presented as soon as you tried). Linux is actually the worst in terms of easily running software downloaded from the internet. If you try running an executable with out the executable bit set, it will fail. Nautilus (a major file browser) gives the standard error for when you try opening a file-type that does not have a program associated with it. And, unlike your description of OSX, you can only enable execution on a per-file basis.
