Windows: error code 0x803f7001 - you can do that
The Windows error code 0x803f7001 is considered one of the most annoying errors because it prevents you from activating Windows 10 using the product key. This happens especially with upgrades. In our practical tip, we will show you what you can do about this error.
Windows activation (error code 0x803f7001) strikes: Enter the key manually
The upgrade can mean that the product key is no longer valid and Windows is therefore not automatically activated. This also results in error code 0x803f7001. If this is the case for you, follow the steps below:
- If you have a backup from the previous version of Windows (Windows 7, 8 or 8.1), then import this backup.
- Use the Windows Product Key Viewer tool to read the Windows product key. Save the key in any form (screenshot, text document, etc.) on a USB stick.
- Upgrade back to Windows 10 and then go to Windows Settings, then Update and Security, and finally Activation. Go to "Activate Windows" and then to manual entry. Then enter the key read out.
- Windows should then be activated, because Windows 10 also works with a Windows 7 or 8 / 8.1 key.
