From what I saw in the documentation, AcceptPause appears to be a read-only property, and there doesn't appear to be any methods that changes it. I found very little information is given on what it actually represents, but it might be a function of the the ServiceType passed to the constructor and/or the current State of the service.

Of course, none of that is Perl-related. That's because your question isn't either. You might have better luck if you look elsewhere (but sorry, I can't recommend anywhere). Once you find out what interface Windows provides (if any) to do this, we can help you call it from Perl.
