Registry cleaners fix “registry errors” that can cause system crashes and even blue-screens.Here are some promises that registry cleaner tools often make: Registry cleaner companies want you to believe that this would result in big performance improvements so you’ll buy their software. They’d stay in your registry until you reinstalled Windows, refreshed your PC, “cleaned” them with a registry cleaner, or deleted them manually.Īll a registry cleaner does is scan your registry for entries that appear outdated and remove them. If you uninstalled the program, there’s a good chance it would leave all its registry entries behind. For example, if the program were registered as the default program for a certain file type, Windows would save a registry entry so it can remember that’s the default program.
