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 only for systems with Windows 7 preinstalled.

The Genuine Microsoft Label (GML) is used only for systems with Windows 8 preinstalled.

A service label shows the build ID and Feature Byte strings, which are needed for system board

replacement.

The all-in-one service label can be found in the location shown in the figure below (pull-out card).
