Registry errors are malfunctions of the windows registry, which indexes information on all hardware and software settings on PCs. If you attempt to load a program but receive an error message or your computer takes an inordinate amount of time to load or shut down (sometimes even hours,) you might have a registry error. Errors in the registry often occur when programs are deleted but remain in the registry. Large amounts of obsolete entries can lead to corruption of the registry files. Spyware and viruses downloaded from the internet can also contribute to errors.
If you think your registry may have errors, the first step is to verify by downloading software to scan for registry malfunctions. There is a lot of downloadable software available on the internet for free that will scan your registry. I recommend a great program, ErrorFix - it will keep your registry error-free and is easy to set up and use.
Sofotex is another good place to start. It has received good user feedback and has a fifteen day trial period. If you scan your computer and fail to find any errors, consider yourself lucky. If not, move on to the next step.
There are two ways to fix your registry. By using system restore, you can reset your PC to the condition it was before the registry errors started. This is a fast and convenient method that requires no software, so if your system restore feature allows you to revert back to a sufficiently early date, you should consider this method.
However, running system restore sets everything back to the date you selected. Therefore, all the programs and files installed after the chosen restore date would be lost. If you have any data from a date after the one that you are restoring, the next step is to back up the necessary files. This is accomplished by either burning them onto a blank CD or copying onto an external hard drive.
Downloading and running software takes less time than backing up files could, so if time is an issue, you might consider using the scanning software downloaded.
Run the restore feature on the free software you downloaded and restart your computer. If the process was successful, your software should be running smoothly and without excessive errors. You should also notice a marked improvement in overall performance.
Even after running the program to fix the registry, there is still one more step; preventing future malfunctions. Download software to block spyware and viruses, and regularly de-fragment your hard drive. With computers as well as health, prevention beats cure.
