❌ azure_genoa can't be used with windows. See help.md

@EgorBo I don't understand the above error message, #320 (comment). I passed "-windows_x64 -arm64", with no mention of azure_genoa. The documentation says that linux is implied when not mentioned, so I assumed that this would really be -windows_x64 -linux_arm64. What am I missing here?

[EgorBo]

@AaronRobinsonMSFT just noticed your question, so windows_x64 is an alias for azure_windows_genoa (because x64 is an alias for genoa, azure_ is the default prefix).

Unfortunately, genoa machine doesn't support windows. For windows on Azure I use pre-built templates and my template is in a different region that doesn't have genoa VMs (it's relatively new cpu on Azure). I can re-direct x64 to Intel by default probably.

But for now, to run on windows-x64 you need -windows_intel
