What problems of a computer can be fixed by a registry cleaner?

A registry cleaner is a program that scans the registry of Windows and removes unnecessary entries from the registry. 

Now, there are multiple problems that a registry cleaner can fix. One of them is solving the problem of missing file errors. If you use a computer or laptop frequently, you might have seen these errors on your screen. 

These errors usually appear when you start your laptop or computer. However, you can easily remove them by clicking the x or the cancer button. But that does not mean that you have got rid of those errors. Whenever you open your laptop or computer again, these errors will again appear on the screen.

A missing file error occurs when the registry of Windows is not able to find a certain file on your laptop or computer. Generally, there are two reasons which cause these errors. 

The first reason is that there is some malware on your laptop or computer. It might not have been removed completely and now it might be bothering you with unnecessary errors again.

Another reason is that an uninstallation process might have been incomplete. It might happen when you shut down your laptop or computer while the uninstallation process is going on.

Hence, if any of these two reasons occur on your laptop or computer, there is a chance that you see those missing file errors on your laptop or computer screen every time you open it.

If you have malware that is not removed completely, you can use the antivirus software on your laptop to find the incompletely removed malware. After finding it, you can remove the leftovers of the malware easily. However, even if you are not able to remove the leftovers of malware it cannot do much harm to your laptop or computer.

On the other hand, an incomplete uninstallation process of software or programs might create some slight problems. The uninstallation process of a software or program might remain incomplete due to a few reasons.

One reason which causes it is when you close the window where the uninstallation process is going on before its completion. 

Another reason can be the fault of the programmers who encoded the software. There is a chance that they might not have encoded the uninstallation process correctly. Thus, it might also cause the uninstallation process to remain incomplete.

This is where a registry cleaner comes in. A registry cleaner is a specialized software or program made for such things. The only purpose of a registry cleaner is to find out unimportant or useless entries or registry keys of the Windows registry.

Hence, when the laptop or computer is not able to find the entry of some file, the registry cleaner can help in finding it. A registry cleaner can also work like a troubleshooter in such situations.

Plus, you can also scan for a specific entry in the registry of Windows using a registry cleaner. To do this, you will have to write the error that is being displayed on the screen, in the search box of the registry cleaner.

Thus, the registry cleaner will specifically look for entries that are related to the error which is occurring in your laptop or computer.

Hence, a registry cleaner is a very useful tool when it comes to removing such errors.
