Labels for the Windows operating systems

Windows

10 Genuine Microsoft

label: Your computer might have a Genuine Microsoft label affixed to its

cover depending on the following factors:

• Your geographic location

• Date when your computer was manufactured

• Version of Windows 10 that is preinstalled

Go to

https://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:

https://www.microsoft.com/en-us/howtotell/default.aspx

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.
