Read Registry Value from Remote Machine via WMI Service using C.You can use below C function to get list of installed programs from remote machine by reading Registry Value via WMI in C.Read Registry Value from Remote Computer in C using Remote Registry Service.
By default, Remote Registry service will be enabled and started automatically in Server editions (i.e Windows Server 2008 R2) but in Client editions, you have to enable manually. ![]() All youll need to know is the namespace (probably rootcimv2 which is default) and the WMI class where the information youre looking for is located. Using Get-WmiObject, we can query all of the available classes in a namespace. Using Get-WmiObject -List, youll be able to see all of the classes in the rootcimv2 namespace. If you need to check classes in another namespace, you can always use the Namespace parameter along with that as well. Perhaps Id like to see what operating system a computer is running. ![]() Get-WmiObject has a ComputerName parameter where you can specify one or more remote computers rather than locally. Ill look at the Win32OperatingSystem class to see what properties are in there. Similar to many other PowerShell outputs, you do not see all of the properties. For that, well have to use Select-Object to return all of the properties. For example, we can query all of the instances in the CIMDataFile class, but that would return every file on the system Instead, we can filter instances by value using either the Filter or the Query parameter. Since the Compressed property is a property on each instance and its a boolean value, I can use the Filter parameter to send the filter directly to the WMI provider only returning instances that have a Compressed property of True. One common WMI method thats invoked is the Create method on the Win32Process class. There are a few different ways to invoke WMI methods such as using Invoke-WmiMethod, but this can be done with Get-WmiObject as well. We just need to capture a WMI instance and then call the method on that object. As a bonus, were using an alternate credential to do so as well. Otherwise, youll need to enable PowerShell Remoting on remote endpoints when wanting to use Get-CimInstance via WSMAN.
