[citation][nom]randomizer[/nom]I'd prefer it if they did away with a registry.[/citation]
The registry is quite fine, much better than hundredths of configuration files scattered in system folders each with it's own format and quirks (after all, the registry is a unified hierarchical database with a well defined uniform API for all applications and system components, optimized for fast access (unlike config files that need constant parsing and knowledge of their format), config files become a mess really soon and they are really hard to repair with a generic tool once broken)
The problem of the registry is the lack of component ownership over registry keys (ownership can be set at user level). If they add component ownership of registry keys, once a component is gone, all keys owned by that component can be automatically purged, while maintaining the benefits of having a system wide database of configuration values with a standard and unified API.
