What is Windows Registry?

In simple words, Registry is a huge database comprised of configuration settings for Windows and third-party programs you have installed on your computer. Mainly, Registry controls how Windows interact with the hardware and software based on user preferences. 

Generally, Registry works fine and doesn’t cause any issues to the user unless someone modifies its content incorrectly; it can really create a mess. Now, you might be thinking that I didn’t do anything, so why am I facing these errors. 

Well, there are a few more factors (which we have discussed in the next section) that can cause the Registry items or entries to be corrupted and damaged. For that, you might face a number of issues in your computer, including excessive CPU utilization, longer startup and shutdown times, poor application functionality, or random crashes or hangs.

What Causes Errors in Windows Registry?

Before we get into the actual methods to solve the errors with the Registry, you must know what caused it to be corrupted in the first place. Below we have gathered some of the potential reasons that could be responsible for causing you the troublesome Registry errors. 

Orphaned Entries: Orphaned registry records are the small fragments in the entries that get left as a residue after uninstalling or deleting a software/program. It’s basically a leftover in the Registry entries that tends to cause issues. 

Duplicate Keys: When you reinstall or upgrade software on your PC, including the operating system, that is when the duplicate keys are made in the Registry. Duplicate keys might be a problem to the particular application they’ve been created by, but the chances of it slowing down your overall computer’s performance is darn low.

Fragmented Registry: Registry files can get fragmented due to the accumulation of several empty registry keys within them. Moreover, Registry can get fragments when an application or program is either updated or uninstalled.

System Shutdown Errors: Every time you turn off your PC, a copy of a registry gets stored in the system memory. At times of power failure and unexpected shutdowns, the machine doesn’t get the time to go through the regular system turn-off routine, and it causes corruption in the Registry hives due to the abrupt stoppage in the process. And later, it presents itself as an error as you try to restart your computer. 

Malware/Virus Issues: Among all the listed issues, this can be occurred as potentially damaging to the device. If the Registry items in your computer have been misconfigured by malware attacks, this should be taken seriously as it requires immediate action. Registry entries installed by malware or trojan programs can’t be removed manually, and in certain scenarios seeking help from professionals can only fix the problem for you. It might also prevent you from launching executable files on your PC by changing file associations. Thus it is crucial to resolve the issue as soon as possible before it brings your PC to its knees.
