Basically the registry stores data for users programs and the OS. Everything from options, to file associations. In comparison, UNIX-like systems use text-files instead of one centralized registry.
Generally, programs should tidy up after themselves, but often they dont. Most "registry cleaners" are a scam and just break things. The only one ive had any success with is CCleaner's registry cleaning function. Its not too invasive, but ive never had any adverse affects from it.
