Lenovo preinstalled operating system and software
What
is
the
Lenovo
preinstalled
operating
system?
Some
Lenovo
computers
come
with
copies
of
the
operating
system
installed
at
factory.
Lenovo
provides
computers
with
a
preinstalled
operating
system
for
your
convenience.
If
you
purchased
such
a
computer,
you
can
use
your
computer
out
of
the
box
and
do
not
need
to
install
a
separate
operating
system.
What
is
Lenovo
preinstalled
software?
This
is
software
(developed
by
Lenovo
or
other
software
vendors)
installed
and
licensed
at
the
factory
for
your
convenience.
The
license
for
some
preinstalled
software
may
be
for
trial
versions.
When
the
trial
period
expires,
you
may
need
to
purchase
a
license
if
you
want
to
continue
to
use
the
software.
Note:
If
a
license
agreement
is
displayed
when
you
first
start
the
software,
read
the
agreement
carefully.
If
you
don’t
accept
the
terms
of
the
agreement,
do
not
use
the
software.
When
I
purchased
my
computer,
it
included
a
copy
of
Windows.
How
can
I
determine
whether
the
copy
of
Windows
is
preinstalled
by
Lenovo?
On
the
outside
of
the
sales
package
of
your
computer,
you
should
find
a
label
containing
configuration
information
for
your
computer.
Check
the
printed
string
next
to
OS
.
If
it
contains
Windows
or
WIN
,
the
copy
of
Windows
was
preinstalled
by
Lenovo.
I
uninstalled
a
preinstalled
software,
but
there
is
no
significant
increase
in
the
free
drive
space.
The
copy
of
Windows
running
on
your
computer
may
be
Compact
‐
enabled.
For
computers
with
Compact
‐
enabled
Windows,
the
majority
of
files
needed
for
preinstalled
software
are
installed
on
the
Recovery
Partition
and
won’t
be
deleted
through
normal
uninstallation.
