Right. Just like how trying to edit the registry requires you to elevate via UAC and then click through the prompt that says "Adding information can cause components to stop working correctly".
Normal users don't edit or see the registry. It's not like we're living in 1995 anymore.
Not keys that don't require elevated privs. I'm not even in the business of "IT" anymore and I get everyone I know and barely know ask me to fix their broken Windows machines. It's 2014 I think. Windows's design is pure garbage, and always will be because it's fundamental to Windows itself (unless Microsoft lends the rights to the trademark Windows to some other OS).
