Hi @Anonymous ,
do you really need the Windows 10 multi-session version?
If "yes" you need one of these licenses (at least this is my understanding, but I am not a licensing professional):
- Microsoft 365 E3/E5
- Microsoft 365 A3/A5/Student Use Benefits
- Microsoft 365 F3
- Microsoft 365 Business Premium**
- Windows 10 Enterprise E3/E5
- Windows 10 Education A3/A5
- Windows 10 VDA per user

If you need just a "normal" Windows 10 license you should pick the a "normal" Windows 10 image for the V;M. This way the Windows 10 license is included in the price of the Azure VM.
