The only officially (permanently) free official Windows from MS I know about is Hyper-V Server 2019. That's a Windows Server 2019 (corresponding to Windows 10) which is restricted to non-GUI Windows functions for running Hyper-V. However, "mainstream" support has already ended.

Edit: There are official evaluation systems (90 or 180 days) here: Accessing trials and kits for Windows
