Unable to activate new Windows 10

If it won't install the key it's likely the wrong version (like "Pro N" etc) - check the edition...

Activation on new hardware

I had already completed the troubleshooting steps you have suggested and the process simply ends up with 'Unable to activate windows'. Error message persists.

 

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
