Example of a COA label
Microsoft Windows "Product Key" of the "Certificate of Authenticity" (COA):
The COA label is only attached to the side of the device when a Windows operating system is
installed.
The Windows 10 COA label has an additional security feature which conceals part of the
product key.
The scratch-off panel consists of a small transparent label with a silver-colored scratch coating,
which was applied to conceal part of the 25-character product key. This scratch-off panel is
designed to protect the product key from being obtained and used by unauthorized third parties.
You usually do not need this product key for commissioning because a valid product key has
already been integrated into the pre-installed operating system.
