(Except for 4) I'm no longer seeing cookies in CCleaner even though sites are telling me that they use them - including my bank.
Is CCleaner stopping them, or is that CCleaner is not finding them?
Prior to upgrading to Windows 10 I used to see hundreds of them!
I had the same problem with 8.1 until I deleted everything via Internet Options as previously suggested.
Now when I run CC it only fails to delete all the cookies without extensions (eg .com, .net etc)
