You may wonder how Windows registry can cause errors on your system. Well, the registry is the repository that stores on your computer all information about system hardware and software configuration, system and network settings, and user profiles. Therefore, each and every PC activity, such as accessing, installing, uninstalling, working on applications, and configuration change, such as modifying display settings, changing audio level, and changing window size, makes an entry or adds a key within the registry.

Normally, an entry or key when no longer used—after you uninstall an application or close a program—are deleted automatically from the registry. However, at times some of these keys are either left behind and leave vacant spaces or registry holes. Over time, a large number of obsolete, redundant, and invalid entries and registry holes accumulate within the registry causing it to grow at an unwarranted rate. Eventually damaging, corrupting, and fragmenting the registry.

Therefore, next time you cannot open an application and keep receiving an error message, then you must know that a registry error might be behind it.

If you frequently browse the Web and download various freeware programs, audio, and games, then your computer opens up to attacks from malware such as viruses, Trojans, spyware, and adware. These malicious programs add embedded keys within the registry. These keys are usually non-removable and cannot be deleted manually. A registry error that is caused due to a malicious entry can cause many serious problems to your system. These entries may change file associations and prevent you from opening executable files and cause system freezes whenever you start working on the system. In more severe cases, registry error due to malware may damage your system hardware and prevent your PC from booting up.

Registry Errors: Fixing

The best way to fix registry errors is by using a registry cleaner software. Registry cleaners are readily available for download on the Internet. However, you must be careful while selecting the registry cleaner for your PC. First and foremost, the registry cleaner you opt for must be compatible with the operating system on your PC. For instance, if you own a Windows XP PC then the registry cleaner you go in for must be compatible with the Windows XP registry. This is important because different Windows versions use different approaches to store information in the registry. If you buy an incompatible registry cleaner, you might end up with more errors than you initially had.

A good registry cleaner enables you to scan and fix each and every registry error with just a few mouse clicks. Registry cleaners help you make regular backups of the registry that you can use to restore the registry to last known working state in case of problem. An advanced registry cleaner enables you to perform a deep scan to weed out obsolete entries, invalid entries, registry holes, and fragments from deep within the registry. An efficient registry cleaner also helps you eliminate embedded registry keys added by malicious software, which are otherwise untraceable and irremovable. Using a good registry cleaner you can also defragment the registry and make the registry files contiguous to ensure faster data access.

A healthy registry is crucial for optimal performance of your PC. A single registry error can considerably bring down your system’s performance. To prevent registry errors, you must regularly run anti-spyware scans on your system. You must also keep your computer updated with the latest virus definitions and security updates. Additionally, you must regularly use a reliable and compatible registry cleaner software to scan and fix registry errors and enhance your computing experience.
