Well.. the above is in most cases a request for a CGI script to execute
on the server, not a download.. it may result in some file of some type
to get downloaded, or in a plain HTML response, or mostly anything
else.. (just as any other HTTP request may..)

mime.conf is only used when Squid has to guess the MIME types, i.e. when
fetching ftp:// objects. For HTTP requests the MIME type is assigned by
the origin server.

In your example above the MIME type of a download from a MS site is
application/x-msdownload, not application/octet-stream, and if you want
to block these downloads you should block replies of mime type
application/x-msdownload.
