ID. The Product ID is important in case you need to reinstall the Windows 7 operating system from a source
other than a Lenovo product recovery disc set.
Windows 10 Genuine Microsoft label: Depending on your geographic location, the date when your
computer was manufactured, and the version of Windows 10 that is preinstalled, your computer might have a
Genuine Microsoft label affixed to its cover. See http://www.microsoft.com/en-us/howtotell/Hardware.aspx
for illustrations of the various types of 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 http://www.microsoft.com/en-us/howtotell/default.aspx.
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.
