How to check my windows server is virtual machine or physical machine

I'm remoting desktop to windows servers in our Lab/datacenter. I have a requirement to figure out all our servers are virtual machines or physical servers programatically, certainly we have the environment sheet tell us which is which. But I need to write code to distinguish it. What technique I need to use? I didn't find a .Net Assembly to do that. Looking for expert to share your knowledge or guidance, any research direction or link, anything will be appreciated!

Solution

You can try to use the following PowerShell script, it utilizes WMI to find out if machine is virtual machine or physical machine.


gwmi -q "select * from win32_computersystem"

Certainly, you can use C# code to query WMI too. The output of script above will be like following:

Domain:   ...
Manufacturer: Microsoft Corporation
Model: Virtual Machine
Name : .....
....
