How to Fix Windows Registry Errors and Boost PC Speed Effectively

September 13, 2011

windows-error-broken-registry Computers require routine maintenance to keep it running at optimal performance just like an automobile requires preventative measures such as oil changes. At times, the computer registry is the culprit of your system running slow or causing issues due to a Windows registry error. In many cases, the key to fixing errors and boosting PC speed lies with finding the root cause of registry errors and repairing them.

Simply running an anti-spyware program on a PC may not resolve all performance hindering issues. The use of a registry repair application may be necessary to detect and fix registry related issues, which could be an underlying problem for your PC and its ability to perform at optimal speed.

Windows registry is the central storehouse for all settings for the Windows operating system. The Windows registry includes data such as hardware and software configuration, file associations, and control panel settings. Thus, as time passes, the registry can become larger and larger. What is even worse, if not maintained properly, the Registry may suffer errors that later on cause system and application problems.

What are Registry Errors and Why Do They Occur?

Causes of Registry Errors

Most of the registry errors are caused by improperly uninstalled applications that leave their left-over files in the registry. Other registry errors are caused by unnecessary files that only use system resources, but are practically useless. Trojans, viruses and other types of malware usually create entries in the registry, which are very difficult to remove and cause system errors.

Types of Registry Errors

Whatever the reason for a registry error to occur, it is a well-known fact that even if a registry error is not as dangerous as Blue Screen of Death (BSOD), it can still hinder the proper performance of your PC. Any error can cause slow start-ups, shutdowns and overall system slow-downs. In other cases, registry errors can even cause an application to freeze or crash. Malware entries that create Registry errors can cause network errors and can even prevent your PC from booting up.

There are different kinds of registry errors. Dll errors are one type of errors that most frequently occur. They are caused by a missing .dll file, which is needed to run the executable files of a given application. There are also registry start-up errors, which occur if a start-up item is improperly configured or even missing. The most scary of the common errors is the Blue Screen of Death, which appears when Windows crashes. In many cases, the computer crashes and the Blue Screen of Death appears when the Windows settings are improperly configured on the registry (for example, if a program makes improper changes in the registry).

Registry Error Effects

Any error can cause slow start-ups, shutdowns and overall system slow-downs. In other cases, registry errors can even cause an application to freeze or crash. Malware entries that create Registry errors can cause network errors and can even prevent your PC from booting up. Any given type of registry error may cause a PC to become unstable and have poor performance to the point that it may become unresponsive.

Registry Error Preventions and Solutions

By properly uninstalling or installing programs you can reduce the chances of a registry error occurring. Utilizing the add/remove programs function in the Control Panel to uninstall applications does not always ensure associated registry entries are removed with the program. Some applications require use of an uninstallation program supplied by the software's manufacturer. By performing frequent malware and virus scans, you can reduce the chances of registry errors from occurring due to a malware infection. The regular use of a registry maintenance and repair tool is essential to keeping your system healthy.

Whatever the reason for a registry error to occur, it is a well-known fact that even if a registry error is not as dangerous as Blue Screen of Death (BSOD), it can still hinder the proper performance of your PC.

Symptoms of a PC with Registry Issues

If registry errors are left unfixed, you could potentially face a plethora of additional system issues that could ultimately lead to your PC crashing. It is important to understand how issues are caused within a PC's registry. Below are several reasons why you may find that you need to fix registry issues.

  • Software that you deleted was never completely uninstalled using add/remove programs or the software manufacture's uninstall application.
  • You frequently uninstall or install programs.
  • You have several unused drivers on your computer.
  • You have installed or uninstalled hardware recently.
  • Embedded spyware or malware loads on your computer at startup.

    Windows Vista is a POS. Runs slow all the time. Tried a few registry fix and it loads about 10 seconds faster. I guess Vista’s registry gets bloated very fast when you install programs. Thanks for fix guys.

  • Milo says:

    JUST GET A MAC! Okay, in all seriousness, GET A MAC. OKay, kidding aside, start uninstalling a few key programs like some of the Adobe products or ones that load into memory when you startup. You will be surprised what happens when you get rid of nonessential programs.

    You forgot to mention USER ERROR is a cause for corrupted registries. Found out my son attempted to edit the registry and deleted a software folder and I could not boot up Windows unless I selected Safe Mode. Luckily, I used a registry scan program and it fixed the problem. Thought I would have to reinstall Windows but somehow he deleted a folder that just needed its association changed by the reg scan program.
