I have been using CCleaner for MANY years now and have always been very happy with it. It is only recently that I went Pro though - with version 5.22, which immediately upgraded to 5.23. I never had any issues until then... I have never got a Windows 10 Message stating it is removing my copy of CCleaner, even when I upgraded to the Windows Anniversary Edition! I'm running Windows 10 Home Version 1607, Build 14931.1000 - the latest in the Slow Insider Ring, on a Samsung Laptop with an i5 Processor, 8 GB RAM, 1 TB HDD, 14" Touch Screen, Built-in Graphics. It is after upgrading to CCleaner 5.
