Removing only Windows executables

I'd love to be doing support on your network!

If a user in the Oak Harbor office of one of my clients needs an executable
file installed on his machine, I normally confirm that he will be at his
desk for ten minutes, e-mail the file to him, and then walk him through the
installation over the phone. Total billable time, probably fifteen minutes.

Under your management, I would make sure I had the user's password in case
he wasn't there when I got to his office, burn the executable to a CD, drive
the 50 miles to Oak Harbor, install the software, probably get stuck for an
extra half hour dealing with other trivial issues, and then drive home.
Totable billable time, at least three hours.

So it's easy to understand why this policy would be a really good idea. Of
course, from the perspective of the stockholders the managers sponsoring
this policy should be taken out and shot, but that's hardly a reason for us
SysAdmins to oppose it.
