I am using CCleaner version 5.43.6522 on Windows 10. Although I have all options for cleaning enabled, CCleaner always skips the cleaning of Internet Explorer or Edge history. It cleans FireFox and Chrome without any problems.
Is this a known problem or am I missing something?
It's usually because IE, Edge, or something that uses their storage, is still running in the background.
Take a look at this from last Saturday, another user had a similar problem and with a bit of testing found that it was IE that was being slow to close.
