If you're looking for a mid-level cleaner and speed is the name of the game, TweakNow is what you want. Although not as deep a cleaner as Comodo, TweakNow RegCleaner is one of the fastest registry cleaners you will ever use.

TweakNow RegCleaner works with Windows XP, Vista, and 7 and does a fantastic job of removing obsolete registry entries. And like CCleaner, I've never seen Comodo System Utilities brick a PC. Once you've run it, you should experience a much-improved system. This registry cleaner should be considered more of a deep cleaner. The System Utilities tool is free, so you can't go wrong. Its products are always topnotch and affordable. Comodo is one of those companies that's not nearly as well known as it should be. This tool will dig a bit deeper than CCleaner but is just as safe. 2: Comodo System UtilitiesĬomodo System Utilities is another product with more features than just registry cleaning.

CCleaner is also a mid-level cleaner, in that it does not go too deeply into the registry, so you don't run the risk of breaking your machine. One of the things I like most about CCleaner (aside from the fact that it will also rid your machine of temporary Internet files) is that it will always prompt you to back up your registry before you run the cleaning tool. I know it gets a lot of flack for having to be run multiple times (to fully clean the registry), but it always does the job, and never have I seen CCleaner render a system unbootable or worse for wear. Here are a few apps you can trust to handle the job and keep your registry as clean as possible (without manually running a fine comb through every entry). There are tons of registry cleaners out there, some of which do what they promise. Aside from being fastidious with your software management, you can use various tools to help keep the registry clean and free from errors. And when the registry gets mucked up, bad things happen. With rampant and careless software installation, the registry gets mucked up quickly. So it behooves the admin (or the user) to keep the registry as clear of errors as possible. From within that hierarchical database, the operating system can be rendered unbootable, slow, or problematic. Along with viruses and malware, the registry is the Achilles Heel of Windows.
