Disable ECDH public server param reuse in Windows Server IIS

ECDH public server param reuse is when a server uses the same DH (Diffie-Hellman) key value for multiple handshakes, instead of generating a new one for every handshake. They should be "ephemeral" though which is why it is called "DHE" or "ECDHE", and this means the key is single-use and should never be reused. Windows Server IIS is known for reusing DH key values, but there is a way to disable ECDH public server param reuse in Windows Server IIS.
