Native SChannel implementation on Windows 10 and Windows 10 Server version 1903 (May 2019 Update) and newer supports TLS 1.3.

This is how you can enable it using registry for the client:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Client]
"DisabledByDefault"=dword:00000000 
"Enabled"=dword:00000001

This is how you can enable it using registry for the server:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server]
"DisabledByDefault"=dword:00000000 
"Enabled"=dword:00000001

Bear in mind that this will have no effect on any versions of Windows prior to 1903.
