If you are a fan of Windows, you must have installed the Windows 10 for almost two years. And for now, it perhaps becomes slower and stuck sometimes, just like its old Windows siblings. Often, you should blame on your system registry; for it is the database of every detail about your computers like listings of your context menu and the pointers to the programs that fire up when you click an icon. Now you may wonder why you should blame the registry for the slowness and freezes. Let’s see how it ends up with something wrong.


Normally, after we uninstall an application or stop a program on Windows 10, a registry entry or key that is no longer used will be removed automatically. However, sometimes parts of these keys are left behind or leave vacant space in the registry. A large number of invalid entries and registry holes pile up in the registry, which might end up with damages and fragments of the registry. When you cannot open software and an error message keeps popping out, you should realize that there might be a registry error.

Therefore, you should clean the registry for your Windows 10? But why should you use a Windows 10 registry cleaner? If you ask a question like this, you may not really have seen the registry. The picture below is what it looks like.

There are millions of keys and values in the registry. If you want to clean it up manually, you have to learn about what every key means and how to set the value. Pay attention! It gets millions of keys to inspect.
