Find Windows 10 license for activation of Windows 11

I currently switched to a new Mac (Apple silicon, M2), and just installed Parallels 19 with Windows 11. My old data from old laptop has been migrated with Windows 10, which is not supported by a new machine. Therefore, I installed Windows 11 and obviously, now I have an activation issue. Microsoft support saying that hey need to get License Key from my Windows 10. I am still have Windows 10 VM file, and files are accessible. The question is - is there any way to find Windows 10 License Key by accessing VM's .pvm file?

 

I have this question also?

 

Well, I called Microsoft support two times already. They keep asking me to provide a Windows 10 License, which I cannot access as the VM has been migrated to the new laptop with Windows 11. Now I have two VMs on my new laptop - 1st with Windows 10 (not functional on M2), 2nd with Windows 11 freshly installed and asking for activation keys.

 

I have this issue as well. I have access to my PVM file and don't know where in the Windows PVM I can find the license key. Microsoft will not provide assistance unless I can provide the Windows 10 Product Key. Catch-22
