Description

The Remove-LocalGroup cmdlet deletes local security groups. This cmdlet deletes only a local group. It does not delete the user accounts, computer accounts, or group accounts that belong to that group. You cannot recover a deleted group.

If you delete a group and then create another group that has the same group name, you must set new permissions for the new group. The new group does not inherit the permissions that were assigned to the group.

Examples

Example 1: Delete a security group

PS C:\> Remove-LocalGroup -Name "SecurityGroup04"

This command deletes the group named SecurityGroup04.
