Installing and connecting the device
3.1 Preparing for installation
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.
● COA label of a device with the Windows Embedded Standard 7 operating system
● COA label of a device with Windows 7 operating system
● COA label of a device with Windows 10 operating system
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.
