+Allow connecting to HTTPS WinRM servers (used with, for example, Enter-PSSession) without checking the certificate. This is not recommended, but can be useful for non-domain-joined VMs that will connect to a remote network over a VPN. (Note that not checking the RDP certificate is no improvement over not checking the WinRM certificate.)
