Is it safe to remove entries from the registry to type libraries that no longer exist?

Question as in title.

Wh开发者_如何学运维en I have various entries in the Registry to a type library, but the actual type library file is no longer on the system, is it safe to prune these entries from the Registry?

Sure, but why would you? There's no adverse effect to leaving them be, but if you make a mistake, you could have tough to diagnose problems down the road.

In general registry "cleaning" is completely unnecessary.
