In the Updated version of Windows 10, cookies are no longer handled the way they were in the past. Running CCleaner generally only shows a listing for a "deprecated" cookie. If you open the location shown by the deprecated cookie you'll probably see a window that says something to the effect that cookies are now handled differently.

FWIW, even blocking all cookies no longer blocks cookies.

I created a shortcut to C:\Users\Jim8\AppData\Local\Microsoft\Windows\INetCache where I can view them and delete them manually.

I'd also close and reopen your browser, and reboot the computer.
