This is a question that is frequently asked by many people. The short answer is “No, they do not”. In some cases, they can actually cause more problems than they solve by allowing users to delete critical registry keys that should not be deleted. While in some cases, the result of deleting critical registry keys may go unnoticed for a while, others are immediate, and can result in system instability, and in some cases, data loss.
It’s important to understand that the reason registry cleaners don’t solve most computer problems is that they are only one component of the operating system. For instance, suppose that you have a failing piece of hardware. You can run a registry cleaner, but that won’t solve the root of the actual issue. Like any mechanical device, the faulty piece of hardware should either be replaced or fixed. Running a registry cleaner will not fix that particular issue, nor will running a registry cleaner fix a problem caused by excessive memory usage from other applications, hardware conflicts, software conflicts, incorrect driver installation, or hard drive fragmentation.
However, registry cleaners do have their use. When uninstalling applications, sometimes registry keys are left behind, and never deleted. Over time, much like junk files, these registry entries can build up, adding unused registry keys, and making the registry larger than it needs to be. In some cases, this can slow down system performance if there are applications that make frequent use of the windows registry. If the windows registry is large enough, it can also impact boot times as well, causing the system to take longer to load.
There are also some registry cleaners that come with various tools that allow the user to optimize their system configuration, PC Heatlh Advisor is one of these programs. Some of these options may include disabling windows prefetch, clearing various cache and temporary folders, enabling/disabling various windows settings, and improving how windows implements certain hardware features.
In conclusion, registry cleaners do not solve all computer problems, as the windows registry is only one of many system components. If problems arise from having an excess of unused or invalid registry keys, then a simple clean of the windows registry certainly won’t hurt, and in some cases may actually improve system performance. However, most problems relating to system performance will not be solved by a registry cleaner alone.
We picked PC Health Advisor as the best registry cleaner because it offers a wide range of tools in the software program. Items like, process scanner for malware, Start-Up Manager, Driver Update Manager, Defragmentor, registry cleaner and the like to name a few. All these programs combined into one easy to use interface will help you gain back your computers speed.
