However, several users have complained that the application takes an eternity to scan, which may be a huge issue if you’re trying to speed up your PC.

Fortunately, this isn’t a significant problem, and in today’s article, we’ll teach you how to solve it once and for all.

What is the process of using CCleaner?

CCleaner is a trustworthy optimization program that will check your system for garbage and temporary files and delete them. It’s important to note that it looks for files connected with both Windows and third-party software.


It may also be used to clear your registry, hard disk, startup items, browser plugins, and other files.

What is the cause of CCleaner’s sluggishness?

Your settings are the most typical culprit, and scanning your PC for every form of temporary file can take longer, particularly if you have a bigger storage drive.

If you don’t clean your computer on a regular basis, the program will have to work more, making it slower.
