How can you force the Windows RDP client to use TLS 1.3 on Windows Server 2022?
I'm currently using the Windows Server 2022 21H1 Evaluation Version. But the RDP client only advertises TLS 1.2. Edge however uses TLS 1.3 so it should work in general.
According to this: https://learn.microsoft.com/en-us/windows/win32/secauthn/protocols-in-tls-ssl--schannel-ssp-
TLS 1.3 should be enabled by default on Windows server 2022. I'm not sure about the evaluation version though.
Could you document how to enable it for the RDP client/server ? I saw some examples on the net for changing the registry to disable/enable specific TLS versions but I don't know if this is required for RDP or other applications.
