CCleaner, as you know, is one of the most powerful utilities of our time, belonging to the class of optimizers that allow you to speed up any operating system or clean your computer or mobile device from junk, duplicate files, etc.
The capabilities of the application itself can be described for a long time, but it can be assumed that for some reason you do not want to use it. How to completely remove the CCleaner program from the computer so that there is no trace of it in the system? This question may seem quite complicated to the average user. Meanwhile, to perform the uninstallation of this application, you do not need to have any special knowledge, and you can perform the required operations using several simple methods, which will be discussed later.
How to remove CCleaner from your computer: standardtechnique
Apparently, even if you are the most novice user of Windows systems, you know that in any OS of this entire vast family there is a special section in which all installed user applications are recorded. It is located in the "Control Panel" and is called "Programs and Features". Thus, speaking about how to completely remove CCleaner from a computer, the decision can be taken as simple as possible. It is enough to go to the specified section, find the installed application there, and then click the uninstall button located above the list.

Many users rightly doubt the advisability of performing such actions, since native Windows tools do not completely remove installed programs, and then users have to independently search the registry for the remaining keys or files on the hard drive, and then delete them manually. Yes, indeed, it is, but not in the case of this application. The fact is that first the program's own uninstaller is launched, and it removes all the components of the optimizer entirely.
How to completely remove CCleaner from the computer using the application's own means?
However, the method described above may not seem quite suitable to many. In order not to call the “Control Panel” (which is quite problematic to do in the same Windows 10), you can immediately find the program directory in the Start menu, and after opening the contents, launch its ownremover.
But if we talk about how to completely remove CCleaner from the computer using the application itself, you can apply a very non-trivial approach.

Since the program itself is both an uninstaller and an optimizer, you can use the corresponding section in the application itself, select this program and click the uninstall button. This will be followed by the launch of the built-in uninstaller, after which all that remains is to wait for the process to complete.
Uninstalling a program using uninstallers
Finally, let's see how to completely remove CCleaner from your computer using highly specialized programs called uninstallers for this purpose. As one of the most powerful utilities, iObit Uninstaller can be recommended. The list of installed applications in this program is very similar to what you see in Windows (the difference is only in the design of the interface).

For complete removal, you just need to mark the applet in the list, press either the delete button on top, or a similar button with the image of a trash can to the right of the program name, and then confirm the deletion (preferably with a checkmark for searching and deleting leftovers in automatic mode, although this, by and large, it is not required, because in this case, as well as when using the previous methods, CCleaner's own uninstaller will work first anyway).
Note: although this is not mandatory, it is advisable to restart the computer system after completely removing the application. For mobile devices, uninstallation can be done directly from the installed applications section and without the use of specialized tools.
