Thanks for your explanations, which makes sense. However, I decided to take another look, and without any doing on my part, I had received another set of cookies. I ran a custom clean so I could actually look at them, and sure enough, one of them was called deprecated.cookie, which contained "Cookies are no longer stored in files. Please use Internet*Cookie* APIs to access cookies." Another was placed by CyberGhost VPN located in C:\Users\<user>\AppData\Local\Microsoft\Internet Explorer\DOMStore\KTO8TC80 called cg6-content.cyberghostvpn[1].xml. It only contained <root></root>, but I'll contact the vendor to find out why CyberGhost 7 places a CyberGhost 6 cookie. But then CCleaner also found 48 Temporary Internet Files totaling 394 KB which includes several images which =may= have come from Microsoft News like a C-MEN Dark Phoenix banner, an Insider News image to watch the cast of IT Chapter 2, etc. And a bunch of "popup*.htm" files, where I found among the contents the string "https://advertiser.cyberghostvpn.com...". I really do have questions for that vendor! But interestingly enough, there also was a file called update[1].htm, which ends in: Document Moved Object Moved This document may be found <a HREF="http://license.piriform.com/update/?p=ccpro...">here So apparently, Piriform is still placing temporary IE internet files (C:\Users\<user>\AppData\Local\Microsoft\Windows\INetCache\IE\...)?

I'm running CCleaner Pro in Windows 10. I almost exclusively use Firefox, and occasionally Edge, but NEVER Internet Explorer. However, CCleaner ALWAYS finds trackers for Internet Explorer, and I can't figure out why. In earlier versions of Windows, IE was part of the OS, so I can see how IE may have taken some action on behalf of the OS, but as far as I know, that's not the case with Windows 10, where Edge is the default browser. Even if you made another browser your default, Windows (web) searches will use Edge regardless. But how does IE fit into this picture, and why does CC find trackers for it?
