[PATCH] windows.html

This superceeds the pervious patch and attempts 
responds to the input received to date.

Thank you, who says writting doc is a thankless task!

Oh - that shouldn't have gone in, the patch below removes that and
attempts to fold in Paul's input.

Later Brian writes:

I have to stop working on this.

I don't see the typo mentioned, hope it's not there.

Thanks for clarifying the situtation. I've updated the doc
to reflect that situation, if it doesn't get fixed in the
next rev then the doc will need another edit instead.

I've not tried this yet.  Currently -i switch is a bit of a tease
since you have to have had the InstallShield mechinism put the
entry in the registry first.  I dream of a wrapper around the
install install.c functionality so it can invoke it from the
command line.

That may be since your account lacks the rights for such heady
operations.  I'm having a hell of time figuring out exactly what
rights the user needs for each part of the lifecycle: install,
boot, service start/stop, etc.

Dale Couch continues

Running -s I see two processes.  Killing the one recorded in PIDFile works,
as long as I've the rights to do so.

Oh my!  The lemmings are breeding, got a go.  - ben hyde
