You should look for a Certificate of Authenticity, or COA when purchasing Windows 10/11 Pro/Home activation/license keys. It is crucial in order to purchase a legitimate product. COAs are a physical or digital proof of the authenticity of software. They are usually included with retail and OEM licenses. The following are 10 important things to remember while dealing with COAs.
1. What is an authentic Certificate?
A Certificate Authenticity label or sticker confirms that the Windows product key is authentic. The hologram typically includes a unique alphanumeric Product Key.
Understanding the way a COA appears like will help you determine whether the key is genuine. It’s usually found on packaging of the product or, in the case of OEM versions, attached to a computer.
2. Check for Anti-copyright and Holographic Features
Genuine COAs have anti-counterfeiting features such as holographic pictures as well as color-shifting pens and fine printing, which makes it difficult to duplicate.
The holographic security features on COAs are simple to spot.
3. Microsoft Resources to confirm the COA
Microsoft offers tools that can be utilized to verify the authenticity of an COA is genuine. Microsoft has instructions and samples on its website for what an authentic COA will look like.
Be aware of these functions so that you are aware of what to expect when purchasing the product key.
4. Be cautious of COAs that do not have Product Keys
A genuine COA for Windows always includes a unique product key. COAs that do not contain a unique product key, or include an unreadable or altered product key should be avoided.
The key should not change and must be clear, legible and official.
5. Purchase through Microsoft Authorized Partners and Reputable Sellers
Purchase only from Microsoft-certified vendors or trusted electronic retailers. They are likely to provide genuine COAs in conjunction with the key.
Avoid purchasing from unknown or third-party suppliers in which the authenticity of the COA cannot be confirmed.
6. Digital Keys Without COA
If you’re buying a retail key or OEM license, it is important that the seller offers the buyer with a digital proof of authenticity. When buying second-hand and refurbished computer equipment, this is vital.
Consider it a major red flag when there is no authentication certificate or COA.
7. Check that the COA Matches the Product
The COA’s details must match the Windows edition you’re purchasing (e.g. Home, Pro 32-bit or 64-bit). Information that is inconsistent or not correct may be an indication of a fake.
If the device has been pre-installed, then the COA must also be in line with the model and brand of the device.
8. Do not accept COAs that show obvious signs of damage or alteration
If you receive an actual COA, make sure it doesn’t look tampered with or damaged. Scratches and peeling could signify the device was taken from a different device or copied.
A damaged COA can also mean that the key was previously used or was not authentic.
9. Be aware that not all COAs are Transferrable.
For OEM versions The COA is linked to the original hardware. This means it cannot be transferred if you replace or upgrade your PC. Check if your COA can be used with multiple devices.
Retail licenses are the only ones that typically have COAs that are transferable. They are more flexible, in the event that you need to switch devices.
10. Keep a copy of the COA for Future Reference
Keep a digital copy or physical photo of the COA along with the product’s key for future reference. It is helpful in the event that the need arises to reactivate Windows.
It is essential to keep it safely in order to avoid losing the key in the event of an COA being damaged or misplaced.
