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.

This example disables the Microsoft.PowerShell session configuration.
