Remote desktop connection not working after CredSSP update

After Windows 10 1803 Cumulative update it's not allowed to connect with RDP to unpatched machines.
To disable security check - create DWORD AllowEncryptionOracle in registry:

HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\CredSSP\Parameters\
Set AllowEncryptionOracle = 2

Be aware that disabling security check makes your machine vulnerable!
