Microsoft are still happy to charge you £220 for a Windows 11 Pro licence... You can buy Windows 10 Pro OEM licenses for less than 20€ online. I did just that for a familiar three months ago. The installation was validated and associated with the Microsoft account no problem. Then you can "upgrade" to Windows 11 free of charge, if that's your thing.
