Delete registered session configurations from the computer.
This is an advanced cmdlet for system administrators to manage custom session configurations for their users.
Syntax Unregister-PSSessionConfiguration [-Name] string [-Force] [-NoServiceRestart] [-Confirm] [-WhatIf] [CommonParameters] Key -Name The names of session configurations to delete. Enter one or more configuration names. Wildcards are permitted. This parameter is required. -force Suppress all user prompts, and restarts the WinRM service without prompting. Restarting the service makes the configuration change effective. To prevent a restart and suppress the restart prompt, use -NoServiceRestart -NoServiceRestart Do not restart the WinRM service, and suppress the default restart prompt. Until WinRM is restarted, users can still use the unregistered session configuration, even though Get-PSSessionConfiguration does not find it. To restart the WinRM service manually, use Restart-Service. -confirm Prompt for confirmation before executing the command. -whatIf Describe what would happen if you executed the command without actually executing the command.
If you accidentally delete the default Microsoft.PowerShell or Microsoft.PowerShell32 session configurations, use Enable-PSRemoting to restore them.
Delete the MaintenanceShell session configuration from the computer, suppress user messages and restart the WinRM service:
PS C:> Unregister-PSSessionConfiguration -name MaintenanceShell -force

PS C:> New-PSSession -configurationName MaintenanceShell
Delete all session configurations on the computer:
PS C:> Unregister-PSSessionConfiguration -name *
