JetClean 

JetClean optimizes the performance of your computer by removing junk files from your hard disk, and also, by scanning and cleaning invalid Windows registry entries. It is a multi-purpose tool that is able to clean browser history, as well as the history of various Windows applications. The program runs on all popular Windows versions and it’s available in a large number of languages.

Many similar applications are just useless programs, as they don’t really fix anything until you buy them. Even more, the errors they supposedly find are not even real. I am always a bit reserved when I test such a program. And I must say that JetClean impressed me in a very pleasant way. I personally verified if the found registry errors, as well as other problems, were real. JetClean proved to be an efficient solution for increasing the performance of my PC, not just another scam.

Its graphical user-interface is well designed. By clicking on one of the three tabs on the main window, you get access to the scanning section, program tool or settings.

Another thing I appreciated is the scanning speed provided by JetClean. In less than a minute, it was able to scan and fix the found errors (yes, the trial version of the program is able to do that).

JetClean is an efficient program that I kindly recommend.
