As in most cases the popups are just annoying and a simple fix. I have purchased cCleaner from Piriform have 3 different license running on windows 10, on two computers and a laptop, I am a computer tech I build and program computers and without rewriting the program I stopped all popups, I'm running the version 564.7613 64bit and all future updates to the program if done this way will have to be downloaded manually and installed if a person is willing to take the chance that the program will not be rewritten again and more features will stop working or change like custom clean or health check. I am right now satisficed with the way the current version operates with Windows 10 version Microsoft Windows 10 Professional (x64) Build 18363.720 (1909/November 2019 Update) and I will probably will not update the program ever again. So I created two firewall rules denning any further contact outgoing or incoming from Piriform on the exe command in the installation files have seen no popups sense Thankyou for the program Piriform I will enjoy it x3. Windows recommends this program and for good reason it does what it says.
