Parameters

-AsJob: Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-ChassisSerialNumber: Specifies an array of strings. Each member contains the chassis serial number of a server.
-CimSession: Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
-FirstSeen: Specifies an array of dates, as DateTime objects. A time represents when the virtual machine first existed.
-LastSeen: Specifies an array of dates, as DateTime objects. A time represents the most recent time when UAL logged a virtual machine.
-ProductName: Specifies an array of names of products. The installed role or specific product in the request is a component of this product.
-RoleGuid: Specifies an array of GUIDs for roles that client's access.
-RoleName: Specifies an array of names for roles that client's access.
-ThrottleLimit: Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
-UUID: Specifies an array of UUIDs for servers. Each UUID refers to the virtual machine.

Prerequisites

Windows with the UserAccessLogging module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.
