Locating ID labels

To assist in troubleshooting, identification labels are available on each workstation.
● All workstations have a serial number (unique for each workstation) and product number. Have these
numbers available when you contact support.
● The Certificate of Authentication (COA) is used for Windows 7-preinstalled systems only.
●
The Genuine Microsoft Label (GML) is used for Windows 8-preinstalled systems only.

replacement.
