If you have a problem with your computer running excruciatingly slow with long program load times, start up times that can engulf polar changes or even sudden hangs when you are browsing the internet, then more than likely you have a bad registry problem. The reason why you should check PC for errors in the registry is because you want and deserve a computer that is always fast and always reliable. Damages and problems in the registry are unavoidable, and they occur in every PC that has ever installed Windows.

While the structure of the operating system is perfect, the human hand behind engineering and program writing adds a level of chaos within the perfect architecture of computers and data. Anything you do, from loading a program, uninstalling one, installing drivers, adding a new hardware and surfing the net, is writing lines and lines of data within the registry. It is sort of the log book that Windows uses to track all the changes done to its system. It also stores all the information it needs to load programs and keeps track of which files belong where.

So when the registry is damaged, it can lead to some catastrophic results. How can it get damaged? Well the most popular ways include when developers write bad programs and there are problems with the uninstalls, which affects the registry by leaving null spaces, zero values and even orphan embedded keys left behind by the removed program. These lead to sort of ‘potholes' within the superhighway that is your computer and leads to slowdowns as Windows tries to navigate around them. And of course, the registry can get damaged when your computer gets infiltrated by viruses, worms and Trojans. Part of their code is to infiltrate the registry and leave bad values and malicious commands for the very purpose of wrecking your computer.

When they are able to slip past your firewalls and anti virus's defences, there is nothing much you can do. While you are able to detect them and remove them with your softwares, the damage that they have done to your registry cannot be reversed by the blunt hands of these programs. Also, when you install new hardware and there are conflicts or problems, there might be an occurrence when null values and bad keys get left behind even after you have removed the bad hardware.

Like any core file within your operating system, the registry needs some level of maintenance and a good way you can ensure that is always smooth and dependable is by using a registry cleaner. 90% of the problems of computer slowdowns and errors/dialogue boxes can be tracked down to problems in the registry. The good news is that there are plenty of excellent registry cleaners and PC sweepers (also they are called) available freely on the internet. All you need to do is to log online and find one; the process is that simple and leads you to not only the reason why you should check PC for errors in the registry, but it also shows you exactly how.
