+And for some more details on using WMI and Powershell, look at using PowerShell 7 and WMI, look at [my recently published PowerShell 7 book](https://www.wiley.com/en-gb/PowerShell+7+for+IT+Professionals-p-9781119644705).
+In chapter 9, I devote a chapter to WMI and using the CIM cmdlets.
+To see just the scripts for that chapter, see my [GitHub repository](https://github.com/doctordns/Wiley20/tree/master/09%20-%20WMI).
+The scripts show you the basics of WMI and PowerShell 7.
