Genuine Microsoft label
The Genuine Microsoft label is provided on the following computer models:
• Some computer models, based on geographic location, that are licensed to use the Windows 8.1
operating system
• All computer models that are licensed to use the Windows 8.1 Pro operating system
The version of the operating system is printed on the label. Lenovo computers that are licensed for use with
the Windows 8.1 operating system are shipped with the Windows 8.1 license key digitally encoded into the
computer hardware. If your computer model is licensed to use the Windows 8.1 Pro operating system, that
license contains downgrade rights which permit you to use the Windows 7 Professional operating system in
place of the Windows 8.1 Pro operating system if you prefer.
