Genuine Microsoft label
The Genuine Microsoft label is provided on models that are licensed to use a Windows 8 or Windows 8.1
operating system. 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 in place of the Windows 8 Pro or Windows 8.1 Pro
operating system if you prefer. 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, or on the power adapter.
