Locating ID labels

To assist in troubleshooting, product, serial, and authentication numbers are available on each computer.
●
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 systems with native Windows 7 preinstalled.
NOTE:
●
The Genuine Microsoft Label (GML) is used for systems with Windows 8 preinstalled.
●
A service label shows the build ID and Feature Byte strings, which are needed for system board
replacement.
In general, these labels can be found on the top, rear, or bottom of the chassis (tower and desktop
configuration). Your computer might look different from the illustration.
