Following Microsoft's decision not to allow CCleaner in Windows 10, it's probably time to reconsider our beliefs.
Will our computer perform better if the Windows registry is correct? Do you know how the Windows registry works? Do you clean the Windows Registry causing more damage to a system?
The Windows registry is a huge configuration database, both for Windows itself and for programs that you install. For example, if you install a program, it will save its settings in the registry. Windows will add some settings for this program.
For example, if the program was listed as the default program for a specific file type, Windows will save a registry entry to remember that it is the default program.
If you uninstalled the program, there is a good chance that it will leave all registry entries behind until you reinstall Windows, refresh your computer, "clean" them with a registry cleaner, or delete them manually.
So what a registry cleaner does is scan your registry for old entries and delete them. Companies want you to believe that this will result in great performance improvements.
If you search the Internet you will not find anywhere a benchmark that shows an increase in the performance of a computer as a result of a registry cleaner.
What is a registry cleaner like CCleaner?
Registry cleaners appeared 10 years ago, when computer performance was not as fast as it is today. In essence, a registry cleaner is a tool that scans your Windows registry for registry keys that are no longer useful because the software that used them has been removed.
It allows you to remove this "weight" from your system. Toolkits like CCleaner claim that by cleaning your Windows registry, you have the opportunity to speed up your computer. Or at least that is what Piriform wants us to believe.
Do we really need it?
No. You see, Microsoft does not have its own registry cleaning tool and does not approve any third party registry cleanup program. It is not accidental.
Microsoft's position is that users do not mind the Registry because they confuse it. Simply put, any teasing of the Windows registry if you do not know what you are doing can cause serious errors that can make Windows inoperable.
So why do so many people choose to use a registry cleaning tool like CCleaner?
Piriform (now owned by Avast) is run by people who do very good marketing. Do not let them fool you. They want you to believe that Windows Registry Cleaner is essential.
Piriform invests in your desire to increase the performance of your computer and serves what you want to hear. Piriform and CCleaner are not the only ones. There are a number of applications that serve the same story: Wise Registry Cleaner, Glarysoft Registry Repair, Frontline Registry Cleaner, Auslogic Registry Cleaner and more.
To clarify something:
Cleaning up your Windows registry will not speed up your computer. In fact, it may have the opposite effect. Do you trust an automated tool to do things that experts do not decide to do by hand? If he makes a mistake without knowing it, and deletes a registry file that is really important, do you know the consequences?
So why bother with the registry if these junk registry files are not harming your computer performance?
Windows is designed to deal with the registry and any possible registry errors. If Microsoft thought that cleaning the registry would help your computer, it probably had a built-in feature in Windows. He has not done so to date because the registry does not need to be cleaned, despite what others say.
Registry keys do not take up space on your computer, so we are talking about kb or mb files depending on the settings and the age of your computer. Windows reading a file of a few kb or mb does not cause any delay. On the other hand, there will be a delay if the registry files are cluttered, meaning that the entries of an application that you removed have been deleted, but the Windows entries for that application have not been deleted, and there is generally some scrap.
