SAPacker Sorry for the delayed response. Our services using TLS 1.0 is no longer permitted per Microsoft policy (nothing to do with the above). Anything below TLS 1.2 poses a security risk to client machines, which is why it is no longer permitted.
That said, a client machine or WSUS server connecting to server sync, may be configured to use TLS 1.0 but our (Microsoft's) services should be requiring TLS1.2. If the client machine does not support TLS1.2 then the connection should fail. In no way should a client machine be required to use TLS 1.2. Note, if you are referring to clients talking to your WSUS server, it is totally up to the admin to decide if the server supports 1.2, 1.1, 1.0 or whatever.
If you have found this to not be the case it is likely a service config problem and I ask you to report it. 🙂
