In a PowerShell console running as administrator enable PowerShell Remoting: Enable-PSRemoting -force
This should be enough, but if you have to troubleshoot you can use the following commands:
Troubleshooting:
  1. Make sure the WinRM service is set up to start automatically.
    • Set start mode to automatic: Set-Service WinRM -StartMode Automatic
    • Verify start mode and state - it should be running: Get-WmiObject -Class win32_service | Where-Object {$_.name -like "WinRM"}
  2. Set all remote hosts to trusted.
    Note: You may want to unset this later.
    • Trust all hosts: Set-Item WSMan:localhostclienttrustedhosts -value *

    • Verify trusted hosts configuration: Get-Item WSMan:localhostClientTrustedHosts
