Not exactly unfortunately, Microsoft has chosen the route of basically
not allowing SLAAC by default, in order to increase privacy. They
instead randomize the identifiers, and those change every few days. So
unless you disable that on an MS system SLAAC is not all that helpful
(and it is enabled by default on both clients, where it makes sense, and
server OS, where it doesn't).
