I agree with Janje and some others here. The solution is clearly stated a few times. Do not uncheck "Hide protect Operating System files (recommended)". There is no reason anyone needs to see them 24/7, even a developer. If you actually NEED to see system
files, then by all means, go check it, do your bit of "under the hood" tinkering, then go back and RE-CHECK it! This is more about COSMETIC appeal than anything that people are complaining about. I am a heavy LINUX OS user, and this kind of thing doesn't happen
in GNU/Linux. But I need Windows for certain things, as many programs do not run "pretty" on Linux. I have Win 7 on my main partition, Win XP on a second, and Lubuntu on a third. I certainly do not need to be viewing OS system files while browsing Windows
Explorer.
