DLLs and registries are valuable data libraries that Windows uses in order to run properly. Because of that, damaged or missing dlls or registry keys can be a leading cause for crashes, freezes, error messages, and they can even prevent you from launching software and Windows features altogether. Unfortunately, registries and DLLs are clusters of data that even advanced users have a hard time tweaking properly without guidance, and even Microsoft advices against it.
