How to find which instance of IE owns a given process

I often have several IE windows open, each with more than one tab.
When my system slows down drastically, I open Task Manager, and sure
enough, there's an IE process that's hogging 500+ Megs of RAM, or
chewing up CPU. Usually it's Youtube, but sometimes not.

I'd like to be able to find which IE Instance / Web page is
responsible for resource hogging. While it's possible to go to the
Applications tab of Task Mgr and find a process that's associated with
that app, the reverse doesn't seem possible via Task Mgr. Is there
any way to do that?

There are ways to find window info, programmatically.
If you want a simple utility then one option might be
to use Process Explorer from sysinternals.com. It shows
running processes with window handles, dependencies,
CPU usage, etc. If you right-click an item you can click
"Bring Window to Front" to find out which window that
item corresponds to.

Thanks. I just DL'd the latest version (2011 sept), and though I don't
see a 'bring window to front', just hovering over the process brings
up a tooltip with the website info. Very helpful.

You can also use the spider-web toolbar button. Click on it and the
mouse cursor changes shape. Then click on the window. PE will
highlight (dark grey, as I recall) the process that owns that window.

Oops...Didn't notice your post until now. Thanks for the reply.

Yes, that would help. I'd have to do things in reverse though--going
through all the windows til I find the one that registers in PE as
using up all the memory.

The primary culprit seems to be Youtube. I'm not sure if it's some odd
interaction with another plugin (I do keep those minimal) or
anti-virus (Kaspersky...already tried disabling protection, but the
problem persists) or just some quirk with Youtube. A Youtube window
will sit there idle, eating up more and more ram, until it consumes
all available memory. I've watched it go over 1 GB.
