Why does CCleaner clean up Internet Explorer items when I don't use Internet Explorer?

Hello Ask Leo!, When I run CCleaner, why does it clean items in Internet
Explorer when I have not used it? This happens all the time. What is going on?
Thank you.

In this excerpt from
Answercast #33
, I look at the reason Internet Explorer files get left on a
system that does not use IE as a browser.

IE is everywhere…

Guess what? You have used it.

I’ve actually covered this before in, probably, a couple of different articles. It’s an easy thing to come at from several different angles.

Internet Explorer and Windows

The fact is that Internet Explorer (or rather the guts of Internet Explorer) is actually used by many other programs; particularly Windows programs.

  • Windows Help, for example, is one of the easy ones to think of.

In reality, the guts (the HTML display engine, those kinds of things) are used by many different programs; both part of Windows, and programs that may get added to Windows later on; that you may install separately.

So as a result:

  • Since the guts of Internet Explorer are being used all the time,

  • That means that all those places where Internet Explorer leaves things that CCleaner would clean up,

  • Well… it’s leaving things there that CCleaner would clean up.

So the fact that you’re not using it as your browser really doesn’t mean that Internet Explorer isn’t being used. It is.

And that means that CCleaner definitely has things to clean up when you run it.

  2. Yeah but, no but, I have UNINSTALLED IE totally! So why is ccleaner showing files from ie constantly? Are you telling me that it is still used thougfh i have uninstalled it? Is there no end to microsofts invasive m.o. !?

    IE cannot be completely uninstalled because – yes – pieces of IE continue to be used by the system. It’s not invasive, unless you consider intelligent re-use of software invasive. Many programs need to be able to display HTML – IE displays HTML – so programs that display HTML are allowed to re-use the portions of IE that display HTML.
