Windows 10: I cannot reactivate windows 11 pro after updating the BIOS. 0x803F700F

I've been searching for solutions and contacting Microsoft Support since last Monday, but no one from Microsoft seems willing to help with this issue. I already created a ticket through their support site and called their support phone line, but they have no idea what a digital license is. I haven't received any help from either option.Error when activating:0x803F700FHow can I reactivate my window 11 pro?

:)

 

Why will Windows 11 Pro not activate? Error code 0x803F700F

Something prevented us from communicating with our activation servers. Wait a few minutes and then try again. Error code 0x803F700F.

I have two valid license keys, global and lifetime.

The Windows 10 key worked fine until I upgraded to Windows 11 (after which I purchased a VALID Windows 11 Pro key), then I got the abovementioned error.

Is there a way of fixing this or will I do I have to buy a new computer to resolve this? Seems rather expensive if that is what Microsoft intends in my case.

 

MSI 5870 BIOS Update

Still can't reproduce. Could you please post the exact BIOSes that produce the issue?

 

Unable to upgrade Windows 11 Home to 11 Pro

Thanks much, Dave, indeed it was a big job.

Clean install of Windows 11 from a bootable USB helped to Activate the Pro.

Just to summarize what was done:

1. Took backup of the drives and save some on cloud.
   
2. Installed the Media creation tool app as you suggested (Download Windows 11)
   
3. Connected the USB and ran the application and downloaded the Windows 11.
   
   1. additional thing which I had to do is to install WLAN driver to the USB in advance, to have the WIFI option available as it was required to connect to a network to download the latest windows features while reinstalling the Windows, and Wi-Fi option was not available.
      
4. Turned off the 'Secure boot' from the BIOS menu.
   
5. Changed the 'Boot Order' in the BIOS menu to first use the USB Boot.
   
6. Saved and Exit, which triggered Restart and Windows installation.
   
7. During the network connecting stage to install the latest updates and features - 'Let's Connect you to a network', I opened the CMD (Shift + F10) and ran than WLAN driver exe to install it and then I was able to connect to my WIFI network.
   
   1. Optional to this step is to BYPASS the network connection stage by following this - bypass "lets connect you to a network" - Microsoft Community
      
   2. Then, doing that manually once Windows has been installed.
      
8. Once everything is set-up, I followed the suggestion from this again, and it worked - Unable to upgrade Windows 11 Home to 11 Pro - Microsoft Community
