Top 10 Buying Tips For Windows 10/11 Home/Pro/Pro/Pro With A Valid Certificate Of Genuineity
Finding an official Certificate of Authenticity (COA) is crucial when buying Windows 10/11 Pro or Home product activation/license keys, especially when you need to be sure that you're buying a legitimate product. The COA can be an actual certificate or digital one that verifies the authenticity of the software. It's typically provided in OEM licenses as well as retail licenses. Here are 10 tips to keep in mind when dealing with COAs.
1. What is an authentic Certificate?

7. The COA must match the product.
The details on your COA should be in line with the Windows version you purchased (e.g., 32-bit vs 64-bit), i.e., Home vs. Pro. Inconsistent or mismatched information could suggest a fake product.
If the device comes pre-installed, the COA must also be in line with the model and the manufacturer of the device.

If you are given a valid COA, ensure that it's not altered or damaged. If you find scratch marks, peeling paint or missing parts, it could be that the COA was removed from the device or copied.
If the COA has been damaged, it could be a sign that the key was previously used or is not authentic.
9. Be aware that not all COAs Can Be Transferrable.
The COA for OEM versions is attached to the original hardware. This means it can't be transferred when your computer is upgraded or replaced. Verify if the COA just for one device, or if you are able to transfer it.
Only retail licenses usually come with transferable COAs, that are more flexible in the event you want to switch devices.

You can keep a physical or digital duplicate of your COA and product key for future use. This can be helpful should you require to reactivate Windows and confirm its authenticity or contact Microsoft Support.
