When you install or uninstall applications, your system is infected by a virus, the system crashes, or many such activities occur on your system, several unwanted, invalid, and malicious entries get added to the registry that unnecessarily cause it to grow to a very large size. A large registry slows down, and as a result slows down your computer. In more severe conditions, registry problems may also cause various computer-related errors, which can eventually crash your system.

This can be completely avoided if you perform certain actions on regular basis to speed up the performance of your computer.

1) Perform Regular Virus Checks

If you are a regular net surfer, and don't care to systematically scan your system for viruses or malware, you are actually inviting trouble. Do you know that you can unintentionally download viruses and malware in your system just by visiting a website? The chances of infecting your system rise if you continue downloading software programs, music, and video clips on your system. Therefore, you must scan your PC for virus infections by using effective anti-virus software.

2) Use Your System Tools

Before you invest too heavily on various types of Windows repair software, you should use the System Tools, which are offered for free with your operating system. For example, you can use the Windows Disk Defragmenter tool to reorganize your files and check the hard drive for errors. The Disk Cleanup tool, on the other hand, helps you remove unnecessary files from your system.

3) Think Twice About Free Downloads

Though you may find it an attractive option to download ?free stuff? from the Internet, but there exist many websites that actually install spyware onto your computer and trace every activity on your computer and display unwanted popup ads. Many other programs secretly add programs to your browser or registry, which can affect system performance and crash your PC sooner or later. So, practice cautions before you click the ?Free Download? button next time.

4) Troubleshooting Errors When They Appear

Do you know that more than 90 percent of computers contain corrupt and significantly harmful files with more than 200 errors? If you ever witness an error message on your screen, you should immediately take action to resolve it. This is because it may gradually start affecting the performance of your system and causing you to reboot, among other things. For example, if you notice a Regsvr32.exe error on your system, you should logon to the Microsoft technical support page and enter the name of the error. This would display a step-by-step process, which you can follow to resolve your problem.

5) Using A Windows Repair Software

Using an effective PC registry repair tool is probably one of the most simple and non-technical methods to tackle the slow performance of your computer. You can opt for an advanced registry scanner or scan your system's registry. This would also allow you to deal with multiple errors at the same time while enhancing the speed of your PC.
