Labels for the Windows operating systems
Windows 7 Certificate of Authenticity: Computer models preinstalled with the Windows 7 operating
system have a Certificate of Authenticity label affixed to the computer cover or inside the battery
compartment. The Certificate of Authenticity is your indication that the computer is licensed for a Windows 7
product and is preinstalled with a Windows 7 genuine version. In some cases, an earlier Windows version
might be preinstalled under the terms of the Windows 7 Professional license downgrade rights. Printed on
the Certificate of Authenticity is the Windows 7 version for which the computer is licensed and the Product
ID. The Product ID is important when you reinstall the Windows 7 operating system from a source other than
a Lenovo product recovery disc set.

Genuine Microsoft labels.
• In the People's Republic of China, the Genuine Microsoft label is required on all computer models
preinstalled with any version of Windows 10.
• In other countries and regions, the Genuine Microsoft label is required only on computer models licensed
for Windows 10 Pro.
The absence of a Genuine Microsoft label does not indicate that the preinstalled Windows version is not
genuine. For details on how to tell whether your preinstalled Windows product is genuine, refer to the
information provided by Microsoft at:

Unlike Windows 7 products, there are no external, visual indicators of the Product ID or Windows version for
which the computer is licensed. Instead, the Product ID is recorded in the computer firmware. Whenever a
Windows 10 product is installed, the installation program checks the computer firmware for a valid, matching
Product ID to complete the activation.
In some cases, an earlier Windows version might be preinstalled under the terms of the Windows 10 Pro
license downgrade rights.
