Error code: 0xC004F034

This was a clean install of Windows 10 Pro (Fall Creators Edition - Build 16299.15). The install had a digital activation for about 24 hours, and then the error code 0xC004F034 popped up. I re-installed Windows 10 Pro and the activation is good, so far. This error makes no sense under the circumstances of the install. I would have to believe that it is a Build 16299.15 issue or the update to 16299.64.

Hi Gilbert,

The error code that you received usually appears when an invalid product key or a product key for a different version of Windows was used. To help sort out this problem, we suggest that you run the Activation troubleshooter.

Hello Rasman,

The Windows activation error 0xC004F034 occurs if you entered an invalid product key or a product key for a different version of Windows. I suggest running the Activation troubleshooter, refer to the steps below:

To use the troubleshooter, select the Start  button, select Settings  > Update & security  > Activation , and then select Troubleshoot.

You must be an administrator to use this option. For more info about the troubleshooter, see Using the Activation troubleshooter.

Update us on the outcome.

I wiped the hard drive and installed Microsoft 10 Pro. I activated windows 10 Pro and went to the Virgin Islands for 3 weeks.  When I returned the Laptop is now saying Windows 10 Not Activated error code 0xC004F034

Thanks for getting back, Gilbert. Did the error come up again after the Windows 10 Pro was reinstalled?

Looking forward to your replied.

Regards.
