It is best practice to always make sure your computer is backed up prior to running any kind of cleaning tool on it. Just make sure you read through everything carefully before using a PC Cleaner since some could potentially delete important data accidentally while trying to repair problems. PC cleaners will also provide other features such as disk defragmenters which reorganize existing data on a hard drive so the operating system can access files more quickly disk compaction which reduces the amount of space occupied by certain types of files such as images duplicate finding shortcut optimizing memory optimization setting customization startup optimizers which defer nonessential tasks from running when startup occurs resulting in faster boot times driver updaters which keep device drivers current with updated versions from manufacturers registry cleaners which scan for invalid entries within the Windows registry database and replace corrupted or outdated entries with fresh new entries from an online repository etc., backup capabilities which allow you to create copies of important documents before making any changes to the system so they can be restored if needed - all these functions contribute toward optimizing PC performance. Once these issues have been identified, the cleaner will proceed to fix them by making repairs or deleting/disabling any offending applications or files.

The cleaner will run scans of your computer's hard drive(s) looking for errors in the file structure as well as identifying potential malware threats. Most PC cleaners come with an easy-to-use graphical user interface that makes it simple to identify problem areas in the operating system. They provide a variety of tools that can help you clean up the hard drive, remove unnecessary files and applications, check for and repair errors on your hard drive, optimize system settings, update system drivers, defragment and compact hard disks, remove viruses and other malicious software (malware), speed up boot times, monitor system usage and temperatures, and more. PC cleaners are software designed to help you maintain and optimize your computer's performance.
