Hello michael neo,

Thank you for posting in Q&A forum.

Activating Windows 10 using a product key can sometimes run into issues for various reasons. Here are a few common causes and steps you can take to troubleshoot:

1.Incorrect Product Key:

• Double-check that you have entered the correct product key. Even a small mistake can cause the activation to fail.

2.Internet Connection:

• Ensure that you have a stable internet connection as activation requires an internet connection.

3.Product Key Type:

• Make sure that the product key is specifically for Windows 10, and not for a different version of Windows or for a different edition (e.g., Home vs. Pro).

4.Product Key Usage: - Ensure the product key hasn't already been used on another device. Windows product keys are often limited to a single installation.

5.Region Restriction:

• Verify that the product key you have matches the geographical region you are in. Some product keys are region-specific.

6.Upgrade vs. Clean Install:

• If you upgraded from a previous version of Windows, you might need to use a different method to activate. Sometimes performing a clean install instead of an upgrade can cause activation issues if the previous installation wasn't properly activated.

7.Microsoft Activation Server Issues: - Sometimes there may be temporary issues with Microsoft's activation servers. Wait and try again later.

I hope the information above is helpful.
