I have Windows 10 64 bit and this issue started last week so this is before and after the Anniversary Update
CCleaner v5.22.5724 64 bit
I have the box checked to empty the recycle bin but it does not empty it, I recently upgraded to the latest version of CCleaner a few days ago and this issue was not present on the older version
This is just a heads up for you guys, maybe its something on my end that i have not done
