Advanced
settings
On
some
computer
models
the
Advanced
settings
menu
includes
a
setting
to
Enable/Disable
HyperThreading.
This
feature
works
only
with
HyperThreading-aware
operating
systems
such
as
Microsoft
Windows
XP.
The
default
setting
for
HyperThreading
is
Enabled.
However,
if
you
select
Set
Defaults
and
are
using
an
operating
system
other
than
Windows
XP,
your
computer
performance
might
be
degraded.
Therefore,
you
should
always
set
HyperThreading
to
Disabled
unless
you
are
sure
your
operating
system
supports
HyperThreading.
