I am sure I am behind the times here but I have noticed that my .../roaming/microsoft/windows/cookies directory is displaying cookies in a random number/letter sequence.txt (3MZCTCB4.txt) file rather than the usual firstname.lastname@example.org
SuperAntispyware reads them like this to. I checked it on another PC and the same thing. Is this a result of a microsoft update or something, was curious thats all.
As a curious side note, I noticed that browsing exactly the same sites in Windows 7 and Vista produced more tracking cookie positives (superantispyware), on Windows 7 than Vista.
