To get a list of service names listed as subkeys under the SYSTEM\CurrentControlSet\Services key in
the HKEY LOCAL MACHINE registry hive, you can use the Enumkey method. This method accepts a
hive constant and a registry path. In this case, you pass the value of the HKEY LOCAL MACHINE hive
and the path SYSTEM\CurrentControlSet\Services, as shown in the following command:

$Reg = [WMIClass]"root\default:stdRegProv"
$HKEY_LOCAL_MACHINE = 2147483650 $strKeyPath = "SYSTEM\CurrentControlSet\Services"
$services = $Reg.EnumKey($HKEY_LOCAL_MACHINE,$strKeyPath)
$services.sNames

Figure 8-35 shows part of the services.
