Common Errors in the Windows Registry

The ‘Windows Registry’ is a central part of any Microsoft Windows operating system. The Registry is a ‘logbook’ of sorts where all the information regarding every installed application is stored, along with details regarding individual users as well as their permissions. It also contains information telling which tells the operating system how to open and run various applications.

Many errors can spring up in the registry due to a number of reasons, slowing down your computer or even making it crash. Some of the most common errors that come up in the Windows Registry are listed below:

Incorrect pre-fetch settings: The Windows Registry contains a pre-fetch option which allows the user of excess RAM as storage for pre-fetched application data. As data has been pre-fetched, application load times are reduced. However, wrong pre-fetch options can cause the entire RAM of the computer to freeze up. Therefore it is important to make sure that you are running on the correct pre-fetch settings.

To check your pre-fetch settings, go to Start, Run, and type ‘regedit’ in the box that appears. Now go to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > SessionManager > Memory Management > PrefetchParameters and look for a key called EnablePrefetcher. If the value of this key is set to anything lower than 4, change it to 4 or 5 and restart your computer.

Slow Registry Access: This is the most common error that comes up with relation to the Windows Registry. This is caused primarily by invalid registry entries related to uninstalled programs which still exist after the program related to them has been removed.

This happens mostly due to users removing applications without making use of the Add/Remove Programs feature. Unwanted registry entries placed by malicious programs could also cause the registry to be cluttered and slow down the computer. The best way to get rid of these unwanted registry entries is to use a registry cleaning application. Another way is to go to the registry editor and deleting entries that are related to applications that no longer exist on the computer.

Although it is possible to fix these errors manually, it is not recommended as improper handling of the registry could cause permanent damage to your computer. Therefore the best way is to use a registry repair software application.
