• Think of PowerShell Remoting (PSRemoting) as psexec on steroids but much more silent and super fast!
• PSRemoting uses Windows Remote Management (WinRM) which is Microsoft's implementation of WS-Management.
• Enabled by default on Server 2012 onwards with a firewall exception.
• Uses WinRM and listens by default on 5985 (HTTP) and 5986 (HTTPS).
• It is the recommended way to manage Windows Core servers.
• You may need to enable remoting (Enable-PSRemoting) on a Desktop Windows machine, Admin privs are required to do that.
• The remoting process runs as a high integrity process. That is, you get an elevated shell.
