I have used the version 2.3 for the past two years.
It has been a great tool to clean up and tune up all my PC’s plus my nieces laptops.
If you want to keep your browser history, untick the selective browser that you use otherwise it’ll clean everything, I mean “everything”.
It will clean up all the windows components files downloaded, e.g. if you happened to upgraded from windowsX to windows 10; once you’ve run this utility, all components downloaded are cleared (unless you kept a copy before you run this tool)
It’s an invaluable tool and I use it regularly.
Thanks very much for the software!
