Diagnosing internet speed issues can be difficult. One has to look at the network card, settings, multiple internet settings hidden in the registry and that's before you get to a possible problem with the router. DNS cache can also be a problem, hence Clean_DNS.

Clicking on the Control button will scan and show you a log file of what entries it found.

Clicking on the Repair button will clean the entries you were shown and once again, show you a log file.

Closing the log files will annoyingly close the application as well for some reason. You can't move or resize the window which always opens at the center of your screen.

The log files will also be saved wherever you run the application, so be aware of that. The log files will be named the date and time you ran it, for example, Clean_DNS_27_06_2017_07.46.54.

Clean_DNS is simple enough to use at any skill level. However, a little knowledge of the DNS cache is helpful. We had no problems taking a leap of faith, running it and rebooting. If you're having trouble diagnosing slower internet speeds, Clean_DNS might just be your missing link.
