I have not changed any software since 5/19/2010 when Outlook 2003 last
worked. I can received e-mail; but cn not send e-mail. When I shut the
computer down, the “Thorconnwndclass program not responding” box is displayed.

How do I use SFC?

I see a lot of web sites at microsoft.com for "Thorconnwndclass"; but no
thanks the problem has been fixed. Has it been fixed?

You could try using sfc, specifically from the recovery console. Its obvious
that one of the required dll file is missing or corrupt, so your best bet
would be to use System File Checker if you wish to avoid a complete reinstall
of Windows to get the problem fixed. This is because despite the version of
Windows you use, IE is an integrated component within Windows which you
cannot reinstall alone. So try out sfc and scan for the missing dll file from
the commandline.

It fixed most of my errors with integral components of Windows. If your not
sure of how to use SFC reply me back.
