Disables session configurations on the local computer.

Syntax

Disable-PSSessionConfiguration
       [[-Name] <String[]>]
       [-Force]
       [-NoServiceRestart]
       [-WhatIf]
       [-Confirm]
       [<CommonParameters>]

Description

The Disable-PSSessionConfiguration cmdlet disables session configurations on the local computer, which prevents all users from using the session configurations to create a user-managed sessions (PSSessions) on the local computer. This is an advanced cmdlet that is designed to be used by system administrators to manage customized session configurations for their users.

Starting in PowerShell 3.0, the Disable-PSSessionConfiguration cmdlet sets the Enabled setting of the session configuration (WSMan:\localhost\Plugins\<SessionConfiguration>\Enabled) to False.

In PowerShell 2.0, the Disable-PSSessionConfiguration cmdlet adds a Deny_All entry to the security descriptor of one or more registered session configurations.

Without parameters, Disable-PSSessionConfiguration disables the Microsoft.PowerShell configuration, the default configuration used for sessions. Unless the user specifies a different configuration, both local and remote users are effectively prevented from creating any sessions that connect to the computer.

To disable all session configurations on the computer, use Disable-PSRemoting.

Examples

Example 1: Disable the default configuration

This example disables the Microsoft.PowerShell session configuration.

Disable-PSSessionConfiguration

Example 2: Disable all registered session configurations

This example disables all registered session configurations on the computer.

Disable-PSSessionConfiguration -Name *

Example 3: Disable session configurations by name

This example disables all session configurations that have names that begin with Microsoft. The Force parameter suppresses all user prompts from the cmdlet.

Disable-PSSessionConfiguration -Name Microsoft* -Force

Example 4: Disable session configurations by using the pipeline

This example disables the MaintenanceShell and AdminShell session configurations. The pipeline operator (|) sends the results of a Get-PSSessionConfiguration to Disable-PSSessionConfiguration.

Get-PSSessionConfiguration -Name MaintenanceShell, AdminShell | Disable-PSSessionConfiguration

Example 5: Effects of disabling a session configuration

This example shows the permissions before and after running Disable-PSSessionConfiguration and the effect of disabling a session configuration.
