Is this possible at all without changing the name of the executable?

It's TeXLive-2005.

In settings->system->advanced->environment I see the value of PERL5LIB.
When I say "set" at the DOS prompt, I see the value twice, once with
slashes and once with backslashes (or vice versa, I can look into it
on monday again).

I understand, though I still wonder how it can be accomplished to hide
TeXLive's Perl reliably from the rest of the system.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
