Just had the newest update to Win 10 the other day , Win 10 Pro v1803 and I am getting exactly the same issues as above , didn't have them before this update.
I have updated to the newest version of CCleaner free.
I noticed it after doing a clean and returning to eBay and finding I was still logged into eBay on IE11 , normally this worked fine and removes ALL cookies.
Manually deleting temporary files in IE11 via Internet Options in Control Panel , General, Browsing history , Delete , worked fine and removed the sign in cookie .
I have nothing on start up that uses IE11 that I know of and I do not get the IE needs to be closed dialogue ? After cleaning CCleaner shows the cookies
have been removed in options / cookies , but if I close and restart CCleaner it shows them as there ?
So maybe it is a bug/glitch ?
I am not writing this to complain , merely to point out that I have the same issue , I love CCleaner and have done for a few years and run it on all
my machines and have never been more than pleased with the results it gives.
