A certificate of authenticity (COA) is a label to help you and your customers identify genuine Microsoft Windows software. Without it, your customers will not have a legal license to run their Windows software.

  • You will find the COA included in the System Builder Pack that you acquired from your distributor. If it is not included, contact your distributor.
  • You must affix the COA to the case of the computer on which you are preinstalling Windows as described in the system builder license.
  • You may not sell the computer without performing this step, So you shpuld buy OEM COA Labels to place on PC's for legal distribution.

The picture above shows the look and feel of the COA used for Windows 8.1 Pro.

Similar to the Windows 7 & Windows 10 COA, it also includes security features to help prevent counterfeiting.
