I often run CCleaner while I am still browsing in Internet Explorer 11. This saves me the time of securely clearing everything (tens of thousands of Temporary Internet Files files) while I am done using the computer for the day.
The latest update of CCleaner does not allow users to clear out the browser data while still browsing... the browser has to be closed. Because of this, I had to switch back to 5.22.5724.
If there is a way to clear browser files using the latest version of CCleaner while still having the browser open, please let me know how to do it.
If there is not a way to do that, my suggestion is to go back to allowing users to begin clearing out the browser files while still having the browser open.
