Common Causes of Registry Errors on a Computer

Has your computer been lagging or malfunctioning lately? This could be due to a problem with the registry. The Windows Registry is an essential part of the computer as it stores the settings for practically everything on your Windows PC. These include device driver information, user passwords, application settings, and more. Your operating system constantly refers to this massive internal database for essential data in order to run smoothly.

1. Malicious entries

When installing new programs onto your computer, there is the possibility that it may come with harmful items such as Trojans, spyware, viruses, adware, and malware. These are known to cause havoc to your system by slowing it down as well as stealing important data such as passwords and files.

These electronic infections can generate entries that can affect core settings reserved for the OS thereby making them hard to find and remove. Hence, it is advised that you should always install a reliable anti-virus and anti-malware program to protect your system from such attacks. This is especially important if you access the internet and download stuff online frequently.

2. Incorrect shutdowns

As a computer boots, the registry is read into the system memory to boost efficiency and speed. The registry in memory continues to be updated while the PC is in use as values and keys are changed. It is not until the system is shutdown that changes are written to the permanent disc from the temporary storage.

In the event of a system crash or power failure, the CPU does not have enough time to complete the read process. Things usually turn out fine but there’s always the risk of a damaged registry when you aren’t mindful. Experts always suggest a proper shutdown to turn off a PC.

3. Orphaned entries

When the uninstall process does not work right, unwanted programs could leave behind remnants in the registry and the hard disk. This is sometimes due to an error but it can also be on purpose. Free trial software, for instance, leaves behind entries so users won’t be able to get more free usage by uninstalling and reinstalling the program.

Orphaned entries might not be an issue if there are only a few of them. However, when the numbers grow, so do the chances of errors and an unstable system.

4. Duplicate keys

When reinstalling, upgrading or updating a program on your system, new keys will be added to the registry. Usually, old keys are not replaced or removed but are instead archived. This often leads to the registry growing bigger in size. In turn, this will make Windows consume more time when searching for the required keys for the program.

Multiple entries can confuse the program causing intermittent problems. Even if this might not be the case, the clutter can still slow down your system.

What Should Be Done?

It is essential to clean your registry every once in a while. This is to avoid redundant files or entries from clogging things up and slowing down your PC. If you believe that your registry has problems, consult a good computer repair professional immediately. It’s good to address a problem early to minimize or prevent any complications.
