IE not fully cleaned

Hotmail always remember my email when I visit. All is checked under IE so there should be not more cookies, forms and such. Why does that happen after soooo many release? IE was NOT running. Newly introduced bug or? I ask because in the past I was just running it without checking really (trusting it).

2 things in a row I find that it does not clean properly... Does CCleaner really works like it is supposed to?

It does because you have "Windows Live Sign-in Assistant" installed.

I don't have this installed but have some LIVE things related so maybe that's it... it should be added in Applications then, no? It would be nice to have a checkmark to 'Delete Windows Live cache'.
