When I open IE8, 6 cookies are created straight away:
atdmt.com
bing.com
live.com
msn.com
windowsmarketplace.com
zune.net
My homepage is set to "about:blank", so I assume that it's some of the default Microsoft toolbars that are creating the cookies. At first sight, this didn't seem to be a problem - all six appear in CCleaner's "Cookies to Delete" section, and are then not in that section after I've run CCleaner.
However, when I looked at the cookies in the Temporary Internet files directory, I found that they're still there, even though they're no longer in CCleaner's "Cookies to Delete" section.
I've discovered that when I open IE8, these cookies are created a second time, and appear twice in the Temporary Internet files directory. When I close down IE8 and run CCleaner, CCleaner only removes each of the cookies once, leaving one of each cookie behind.
I expect that I can solve this by deleting the cookies manually, but thought that I ought to let people know just in case it's a bug with CCleaner.
I only discovered this in the first place because NIS2009 picked up the atdmt.com cookie as a tracking cookie.
I hope I've explained myself well enough.
Update (2009-10-06 19:17). I've just remembered that I cannot delete the cookies manually using Windows Explorer. I'll try rebooting into Safe Mode to see if that helps.
