How to Fix Activation Error 0x803fa067

Error 0x803fa067 is caused by several things, with the most common being a recently installed update, that has otherwise altered or corrupted integral Windows files or a counterfeit copy of the operating system. When Windows 10 was first released, Microsoft was offering a free upgrade for owners of a legitimate copy of Windows 7 or 8. So if you were running one of these versions of Windows, you could go from that directly to Windows 10 Pro edition.

Error 0x803fa067, being an activation issue, is accompanied by the following error message:

Windows on this device because you don’t have a valid license or product key. If you think you do have a valid license or key, select Troubleshoot below. (0x803fa067)

The error itself, is said to occur during the actual upgrade process. Unfortunately, when the problem first came to the fore, there were no real solutions of resolving it. As a result, many people opted to purchase a new digital license for Windows 10. However, several years later, there are now a number of solutions, all of which have proven effective at fixing this problem. That said, before we cover the solutions, let’s first take a deeper dive into the possible causes.

What Causes Activation Error 0x803fa067?

Error 0x803fa067 occurs when the end user attempts to upgrade their Windows operating system to Windows 10 Pro edition. This means it can occur on Windows 7, 8 and 10 home edition operating systems. Below are the most common reasons why this error occurs:

• Illegitimate Copy of Windows: If you have a counterfeit copy of Windows, the license that accompanies it, will causes an error to occur, during the Windows 10 Pro upgrade process.
• Recently Installed Update: If you attempted to upgrade your system, right after installing an update, it’s possible the update is the cause.
• Invalid License Key: If the error occurs during the activation process, then it’s likely due to an invalid/incorrect activation key, or a corrupted Windows build.
