CCleaner is by far the most popular cleaning program and the most frequently downloaded on the Internet in its category. No wonder: the program removes information garbage from your hard drive and from the Windows registry, and thoroughly erases traces of use.

PC-Cleaner: removing data garbage and browser traces
Since the security provider Avast acquired the maker of CCleaner Piriform in 2017, the popular cleaner has changed its face. If you used to have to go through endless lists of configurations to clean your computer, the new “Health Check” is now a starting point for the program. The Piriform manufacturer has introduced this feature since version 5.57 and made it a standard cleanup: it shows not the usual multitude of settings, but an assistant that determines the “health” of the computer – and points to further optimization potential, which, however, is only possible with the paid Pro version.
After clicks, CCleaner will optimize what it finds if you need to scan your PC and fix problems. Disadvantage: Users will not know exactly what the software detects and removes here. It is possible that data that you would like to save will also be lost. Don’t worry: you can always go back to the old search function via Advanced Cleaner . There you can set the search and delete area for Windows and other applications . Then click “Analyze” , and once the search is complete, you’ll get a detailed prediction of the deletion. By clicking on Start Cleaner, it performs the cleanup.
Reg Cleaner: Clean the registry
In addition to data garbage and browser traces, CCleaner cleans the Windows registry database (“Registry”), where the operating system saves all settings. A lot of data junk also accumulates here over time, faulty links can even lead to problems with Windows. However, even cleaning the registry is not without risk. To safely clean the registry, do the following:
- Press “Registry”. , “Scan for errors” and wait for the scan.
- Click View Selected Problems…
- Save the entries you want to delete by clicking Yes and Save and clicking Correct selected errors. Since deleting registry entries may reveal more problems, repeat the process until no new findings appear.
- If there are problems with Windows and other programs after cleaning, double-click the *.reg file saved in the previous step and confirm by double-clicking Yes to reset the changed values.
CCleaner Free: Free Features
Even in its free version, CCleaner offers many add-ons that make it even more valuable. Here is an overview of all the extra features:
