Sane default values on missing reg values

[NiKiZe]

Is there any specific reason behind not trying to use sane fallback values if registry values is missing?

I could think that this is a good thing if one wants to ensure that all registeryvalues are set. but if all values could have sane defaults maybe that is not needed?
