    Top 10 Registry Cleaners

    The problem with Windows is that it does not clean up the registry quite efficiently. Whatever task you perform gets recorded by the Registry, from installing a brand new application to visiting a website. Just run regedit to open the registry editor and navigate through HKey_Local_Machine > Software to check the entries. You will find numerous unwanted or incorrect entries not cleaned up by Windows, leading to a system slowdown.

    The most viable solution to system slowdowns is a system scan with a good virus removal tool and registry cleaner. The antivirus program will remove any spyware/Trojans and the registry cleaner will scan the system for unwanted and incorrect entries and remove them immediately.

    However, one needs a good registry cleaner that catches the maximum errors and is easy to use. You will find many free and paid registry cleaners, but you must be aware of any spyware threats. To make things easier for you, here’s a rundown of the 10 best registry cleaners that have a simple user interface and are able to catch maximum incorrect and unwanted entries recorded by the Windows Registry:

    10. PC Tune-Up

    PC Tune Up PC Tune-Up is one of the best computer tune-up utilities that defrags, backup and cleans up the clutter and repairs the registry quite efficiently. With a nice circular flow chart, the software explains how it will speed up your PC. It first makes a registry backup and then scans for problems, which are then repaired by removing errors in file extensions, uninstalls, paths, shared DLL's and many other sections of the registry. After a thorough scan and repair, the program defrags your computer, which is the final step in making your PC clutter-free.PC Tune Up 

    The best part of PC Tune-Up is its simple interface. Even novice users can use it without any problems. There are advanced settings for advanced users as well. You can try it for free and then buy PC Tune-Up for $29.95 if you are satisfied with the results. The free version lets users scan and repair their registry, but is limited to only five uses.

    9. Registry Tune-Up

    Registry TuneUp - One of the 10 Best Registry Cleaners Registry Tune-up is one of the most effective tune-up utilities that optimize the Windows Registry to enhance system performance. It allows users to ignore the ones they think is not safe to remove from Windows Registry. Users can build their own ignore list to prevent key registry entries from getting removed, thus having complete control in the registry optimization process. The program also has an undo option to prevent any accidental deletions.

    Registry Tune-Up has two modes: Normal and Advanced. While the Normal mode easily suits novice users, the Advanced mode is for users who want a thorough cleanup and other features that improve the registry. In this mode, the software decides automatically whether the entry of the entire sub-key has to be removed. With so many features, this free registry optimizer is one of the 10 best registry cleaners of the decade.

    8. Advanced System Optimizer

    Advanced System Optimizer Home Screen This software is basically a collection of diagnostic tools that optimize your system to improve its performance. Its registry cleaner is quite efficient in removing unwanted entries that are created each time a user installs or uninstalls software on his system. The registry utility then defrags and rebuilds the registry to ensure a smoother performance.Advanced System Optimizer Registry Optimizer 

    Besides the registry cleaner, the program has a host of other tools, including a system cleaner which deletes unnecessary files and a nifty hard disk optimizer that defragments the PC hard drive to ensure hassle-free PC performance. There’s also a nice driver updater that installs your PC with the most up-to-date drivers on your PC. Additional utilities include a smart memory optimizer and a game optimizer that improves gaming performance.

    While the additional utilities are note-worthy, it’s the registry cleaner that most users will look forward to when downloading and installing Advanced System Optimizer. In my opinion, the registry cleaner is quite okay, but then you will have to shed a few bucks to get this service as the free version scans the system and does not remove the registry. If you are ready to pay $39 for this all-in-one optimization tool, then it can be a good choice. But, if you want a registry cleaner only, then I would suggest you go for free utility options such as Easy Cleaner and Comodo System Cleaner.
