  The 1968 discovery of the Crab and Vela pulsars in their respective supernova
remnants (SNRs) confirmed Baade and Zwicky's 1934 prediction that supernovae
form neutron stars. Observations of Pulsar Wind Nebulae (PWNe), particularly
with the Chandra X-ray Observatory, have in the past decade opened a new window
to focus on the neutron stars' relativistic winds, study their interaction with
their hosting SNRs, and find previously missed pulsars. While the Crab has been
thought for decades to represent the prototype of PWNe, we now know of
different classes of neutron stars and PWNe whose properties differ from the
Crab. In this talk, I review the current status of neutron stars/PWNe-SNRs
associations, and highlight the growing diversity of PWNe with an X-ray eye on
their association with highly magnetized neutron stars. I conclude with an
outlook to future high-energy studies.
