Genuine Microsoft label
The Genuine Microsoft label is provided on models that are licensed to use Windows 8 and Windows 8.1
operating systems. The version of the operating system is printed on the label. If your computer model is
licensed to use the Windows 8 Pro or Windows 8.1 Pro operating system, that license also permits you to
use the Windows 7 Professional operating system. Lenovo computers that are licensed for use with a
Windows 8 or Windows 8.1 operating system are shipped with the corresponding license key digitally
encoded into the computer hardware. Depending on the computer model, the Genuine Microsoft label can
be on the computer cover, under the battery pack, or on the power adapter.
