One work-around for this that I have long advocated is making the
temporary
internet folders and the temp folders non-executable.

This is really a beautiful solution, however, as far as my testing shows, it
breaks Microsoft Office 2000 Premium Setup (the moment when you are prompted
to enter the serial number, and possibly at other places also), and possibly
other installers depending on Microsoft Installer technology as well. Or, I
may have had made the folder non-executable, but my ACLs were somewhat
wrong.

Several others have pointed out the same thing. The temp internet folders
aren't a problem - these really only need to be read-write. In terms of
installing software, using an account other than your normal account to
accomplish that would be the way to go (RunAs under Win2k helps). Or
considering that I don't install software every day, but I do surf the net,
etc. every day, I could script removal and replacement of the 'X' bit, so
set it back, do my install, then reset the permissions.

I understand that this isn't workable for the average end-user, but for
those of us who are a little more adept and security-conscious I think it
might help.
