Disable PowerShell Remoting

Here are a few quick steps to "undo" the default changes performed by Enable-PSRemoting.

PS C:\> Disable-PSRemoting -Force
WARNING: Disabling the session configurations does not undo all the changes made by the Enable-PSRemoting or Enable-PSSessionConfiguration cmdlet. You might have to manua
lly undo the changes by following these steps:
    1. Stop and disable the WinRM service.
    2. Delete the listener that accepts requests on any IP address.
    3. Disable the firewall exceptions for WS-Management communications.
    4. Restore the value of the LocalAccountTokenFilterPolicy to 0, which restricts remote access to members of the Administrators group on the computer.
PS C:\> winrm delete winrm/config/listener?address=*+transport=HTTP
PS C:\> Stop-Service winrm
PS C:\> Set-Service -Name winrm -StartupType Disabled
PS C:\> Set-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System -Name LocalAccountTokenFilterPolicy -Value 0 -Type DWord
