Windows leaves behind so many temporary files and archives that it can soon overwhelm your PC. HackCleaner is a program designed especially to release memory occupied by temporary archives, unessential files and those that are simply hogging space unnecessarily on your PC.
With HackCleaner, you can analyze your hard disk for such problems and it presents a list of all the temporary archives that are no longer needed such as DLL's in disuse, remainders of programs that have been uninstalled plus many other components. From here, you can select the type of archives that you want to delete and afterwards it will present a result of how much space has been freed on your hardrive.
This program does it's job well but it really doesn't offer much more than any other cleaner including Windows own "free hard disk space" cleaner that kicks in when disk space reaches critically low levels. On the other hand, it does give you more detail about what you are deleting and could prevent you deleting essential files by accident.
