iis security : how to tell if an email from MS is real or a hoax?

I received this, and several e-mails like this, and can't
tell if it and the exe file it contains is really from MS
or a spoof. Somewhere on the MS site it says: beware of
hoaxes; MS will not usually send complete files, but will
direct you to the link you need. This is what the e-mail
contained:


MS Customer

Okay, the key here is that MS will _not_ send complete files.

Everything that Microsoft issues for public consumption is available from
their web site, or by ordering from them on CD.

Never open anything that you get in your email that "comes from Microsoft",
because if you didn't sign up specifically to receive it, you won't get it.
Microsoft doesn't send spam [they might blur the lines a little by sending
you an email that's only vaguely related to the list you signed up to, but
that's more a matter of interpretation].

Even those of us signed up to receive security bulletins and other
notifications have not yet received a file in our email from Microsoft.
They won't do it, because they know that too many viruses propagate that
way, and you have _no_ way of knowing whether or not the message came from
Microsoft.

If you ever receive a message that you think might be from Microsoft, urging
that you run this or that upgrade, delete the message, open up Windows
Update (or visit the web site and go searching, if you feel like it), and
see if it offers anything for download. Every time I've received a security
bulletin in my email, the Windows Update site has the software ready for
download.

Remember, Microsoft's customers are a big, shiny, red target, as far as
virus writers are concerned. As a target, it's your responsibility to take
evasive action. Be distrustful. Download the patches yourself, from what
you _know_ to be Microsoft's web site, not from what you _think_ might be
Microsoft's email.

Alun.
