I've noticed similar behavior on two computers that I recently upgraded from Windows 7 to Windows 10. A few observations: - Suggested Sites is not (and has never been) enabled on either of these computers (Internet Options > Advanced tab > Browsing: "Enable Suggested Sites" is unchecked). - This did not happen on Windows 7 (ie. prior to upgrading to Windows 10) and does not occur on another computer I have with Windows 8.1. It appears to be unique to Windows 10. - If I exclude the file "C:\Users\[username]\AppData\Local\Microsoft\Windows\INetCache\Low\SuggestedSites.dat" in CCleaner and then manually delete it, the file will still get recreated when I run CCleaner. - If I exclude the file in CCleaner and do NOT manually delete it, the timestamp on the file will change, indicating that it's been recreated. - If I uncheck "History" under "Internet Explorer" in CCleaner, the file will not get recreated. Of course, this means the IE browsing history won't be cleared either. - (Note that since the file "SuggestedSites.dat" is a protected system file, you must go to "Control Panel > Folder Options > View tab" and uncheck "Hide protected operating system files (Recommended)" too see it in File Explorer.) - I'm using the lastest version of CCleaner (5.18.5607). Since this only seems to be affecting Windows 10, is this a "Microsoft" issue? I was going to suggest updating CCleaner to check if the file is empty before attempting to delete it (so it wouldn't get repeatedly recreated), but that doesn't seem to be the trigger, since the file gets recreated even when it's excluded in CCleaner or "Temporary Internet Files" is unchecked. I'm not sure what files CCleaner is deleting and/or modifying for the "History" portion of "Internet Explorer" but this seems to be the source of the problem. Is this something the CCleaner developers could investigate? Thanks for your help.
