For what it's worth, in a possibly related situation we just
encountered something similar.  In our case it was not a service,
but a COM server (using ctypes or win32com, running as LocalServer32
which launches pythonw.exe in the background).  On my machine
I've had no troubles, but on a remote machine there were
"access denied" errors whenever the developer tried to "-unregserver",
which removes the registry entries.  I believe he tried removing
them manually as well, but could not.  It was a long-distance
thing, so I couldn't troubleshoot it myself...

I theorized there was a leftover process running, but after
checking over the task list he insisted there was not anything
active that could be doing this.

A reboot cured the problem, and so far we haven't seen it

He definitely had administrative rights, so it wasn't that.  I'm
positive it was a leftover "lock" of some kind, but I don't
know anything about that area of Windows so we just moved on.

My point is that it may not even be limited to the service
stuff, but could be a little broader, maybe more fundamental
to doing these kinds of background things using Python
under Windows.
