The registry is located on the hard drive


The registry of the computer is important for keeping information about the user and the applications currently installed inside it. It is a part of all Windows computers. This is present for all versions, from 95 until Windows 10. Although it is an important part of the computer’s processes, it is often overlooked whenever maintaining the PC. Most users may want to regularly maintain the recycle bin and check the viruses for the computer but rarely checks up on the registry’s health.  

Windows’ Role

Without manual checkup, Windows can still regularly keep the registry up to date in terms of writing data about the applications that are currently installed in the computer. It always updates itself to make way for newer applications. However, its problem mainly lies on its unreliability in terms of cleaning itself from old entries especially if the applications are already uninstalled. Often, uninstalled applications delete their files in the hard drive but fail to remove its entries within the registry. This may cause the computer’s processes to be slower than ever. The user may also receive error messages.  Keep reading to find out what the best registry cleaner for your system is as we have ranked the best of the best programs on the market right now.

Why is it important to maintain the registry?

Maintaining and cleaning the registry are important to ensure that the computer’s processes will always be fast. Aside from this, it is also important to ensure that any type of malware and virus will not cause long-lasting damage to the computer especially if it had damaged the registry. Lastly, hackers who may want to steal the private information from your computer which is usually stored in the registry can be stopped by ensuring that the registry is always cleaned. After all, the information stored here can be personal ones such as your basic info up to your credit info. 

What is a registry cleaner?

A registry cleaner is an application that automatically does the job of cleaning and maintain the registry with only a couple of clicks from the user. Although you can manually do this, amateur users may find it hard to do. There is also a risk of accidentally deleting important entries within the computer or changing the wrong setting. A registry cleaner ensures that any entries from uninstalled applications will be deleted. The computer will also have a better performance once its registry is optimized. It may also have a faster process for starting up as there will be less registry entries to load.

First, it has a startup optimizer tool. This can be used to detect which applications open alongside the computer. In case users want to lessen this, the application can show a list of all these applications and allow the user to choose the ones which should open during startup. Having less of these is important to have a faster startup process. 

Its main tool is its registry defrag tool. This is the main tool that can be used for lessening entries that are from uninstalled applications and for reducing clutter within the registry. The application is effective in doing this and is capable of increasing computer performance. With RegClean Pro, users are also allowed to select or deselect certain areas from being optimized by the application if they want to avoid having any issues with it. It is advised to do a full optimization for the registry, though.
