官方解释那张‘破纸’（COA）
To confirm that you have a genuine Microsoft Windows operating system, look for the Certificate of Authenticity (COA) affixed to the body of your computer. COAs cannot be purchased separately. Each preinstalled Windows COA features the Microsoft product name printed near the top of the label and a 25-character product key. If your COA does not match one of these, you may have a previous version.
The latest preinstalled Windows COAs contain interwoven threads with well-defined letters that run through the center of each Port-Hole™.
The top COA displayed on the left has been in production since September 2006 and is available in three colors: blue, rose, or green. There is one transparent Port-Hole™ near the middle of the COA, shaped like a flying window, with individual paper fibers visible around the inside edges. (There may be variation to the shape due to manufacturing techniques.)
The bottom COA, available in yellow, green, or rose has been in production since September 2006. There are two transparent Port-Holes™ located in the middle of the COA. The Port-Hole™ on the left is an oval and the Port-Hole™ on the right is shaped like a flying window, each with individual paper fibers visible around the inside edges. (There may be variation to the shape due to manufacturing techniques.)
