The Cygwin-based Sage-Windows installer has not been released for SageMath 9.4 or SageMath 9.5 yet.
To get the latest version of Sage running on Windows, one option is to activate Windows Subsystem for Linux (also known as WSL), select WSL2, and install any Linux distribution there, then follow the Linux installation guide. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
