I just updated CCleaner Free to vs.5.20.5668 (64-bit) and then did a normal clean. When the clean was finished I noticed that the "Recycle Bin" was not listed in the items cleaned. I checked and found that the Recycle Bin still had content in it - so I emptied it manually.
See image attached.
Just a heads up, as I know CCleaner is supposed to empty the recycle bin too.
