PowerShell cmdlets are most useful in Windows Server environments that don't rely on a graphical user interface (GUI) to configure software.
PowerShell cmdlets should not be used as a replacement for a full network policy management infrastructure, such as Microsoft Endpoint Configuration Manager, Group Policy Management Console, or Microsoft Defender Antivirus Group Policy ADMX templates.

PowerShell is typically installed under the folder
