Genuine COAs have anti-counterfeiting features such as holographic pictures, color-shifting pens, and fine printing which makes them difficult to duplicate.
Be sure to look for these security elements that are holographic, which are designed to aid in identifying fake COAs.

A genuine COA for Windows always includes a unique product key. Be cautious of COAs that don’t have a valid product key or when the key to the product is unclear or modified.
The key should be presented in a clear, readable format, without any modifications.
5. Purchase from Microsoft Authorized Partners and Reputable Sellers
Be sure to buy from Microsoft-authorized partners, certified vendors, or reputable merchants. They are more likely to give genuine COAs with the product key.
Buy only from reputable sources. Avoid buying from unreliable or third-party sellers.
6. Digital Keys without COA
If you’re buying the retail key or OEM license, it’s essential that the seller gives you an authentic digital certificate. This is especially important when buying refurbished or second-hand computers.
A COA or another proof of authentic is not provided. This could trigger an alarm.

The COA’s details should match the Windows version you’ve purchased (e.g. pro, home, 32-bit and 64-bit). A copyright product could be identified by inconsistent or mismatched details.
If the device comes already installed, the COA must match the model and the manufacturer of the device.

If you receive a COA by mail Check to see if it looks altered or damaged. Peeling, scratches or missing sections may indicate that the COA was taken or copied from a different device.
The COA can be damaged if the key is not authentic.

If you’re using OEM versions the COA will be tied to the original PC hardware. It is not transferable in the event of replacing or upgrading your PC. It is important to know if the COA you’re using is for a specific device or if it’s able to be transferred.
The majority of retail licenses don’t include COAs. They are transferable and more flexible.
10. Keep a copy of the COA to be used for Future Reference
Store a digital photo or copy of the COA with the product’s code for later reference. This is helpful if you need to reactivate Windows.
It is important to store it safely in order to avoid losing the key in the case of an COA getting damaged or lost.
Other Tips
Examine Serial Numbers. Some COAs may have serial numbers that can be confirmed with the seller or manufacturer.
Do not remove COAs from the original Hardware: OEM licenses require that the COA remain on the hardware.
Keep receipts: When purchasing an license that comes with the COA it is recommended to save the receipt as proof of your purchase.
