Windows 10: Unable to activate Windows 11 properly

Everything was fine at first. I was using Windows 11 normally, but one day I decided to change the memory frequency settings in the BIOS... and then the entire system started to reboot endlessly. I had to use advanced repair tools to reset the whole system. I lost some files and applications, but I was able to boot into the system normally. When I restored everything, I suddenly realized that Windows was not activated properly. My Microsoft account has a digital activation certificate, so this is quite strange.

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
