Windows 10 Activation Error: 0xC004F034

Hi Greg,

This error code is usually caused by a problem with the product key. For better assistance, we would like to clarify how you got the Windows 10 Pro? Is it supplied by a company?

As an initial troubleshooting step, we suggest that you run the Activation troubleshooter and try activating Windows 10 Pro again. To run the Activation troubleshooter, follow these steps:

• Click the Start button and select the Settings
  icon.
• Choose Update & Security from the list.
• Select Activation in the left pane of the window.

If your Windows 10 Pro is supplied by a company, we recommend that you get in touch with your organization's support for assistance with the activation.

We'll be waiting to your reply.

 

Can't upgrade from Windows 10 Home to Pro

Hi Bill,

Thank you for posting your query in Microsoft Community. We apologize for the inconvenience caused and will assist you in the best possible ways.

I suggest you to download and create an installation media for Windows 10 Pro form the link provided below:

Download Windows 10

After the installation media is created, suggest you to upgrade to Windows 10 Pro from the installation media. When the upgrade asks for product key, enter the product key purchased for Windows 10 Pro. If it does not accept, suggest you to skip the activation
step. After the Operating System is installed, suggest you to activate by phone by following the steps below:

• Press “Windows key + R” and type “slui 4” and press Enter.
• Select the Region from the list and click Next.
• Call the Toll-Free number provided on top and can activate via phone.

Windows 8.1 pro + WMC key activation

I was considering buying a WMC pro add on for my windows 8.1 pro install, but have googled and found some people had trouble activating it. Has anyone on here got any experience with this.

As to my install, I have a real Windows 8 pro key. So I installed windows 8 pro using a MSDN retail .iso which was activated soon as it finished installing , then I updated to .1 pro.

When you buy the WMC add on, it changes your key, I have read some people have had trouble activating it, now mine activates from windows, I hate doing the phone activation crap, so I don't want to have to do that after the WMC add on finishes installing.

The question is, what happens to my windows 8 pro key, is it still usable? and how would i go about if I had to reinstall? would it have to be-

Install win 8 pro-update to 8.1-install WMC add on, or could i use a windows 8.1 pro with WMC disc?

Thanks guys
