How to detect if my application is running in a virtual machine?

Question

How can I detect (.NET or Win32) if my application is running in a virtual machine?

Answer 1

Remember you should not just check popular VM model,manufacturer name from wmi, You should also check difference between reality and virtualization.
VM don't have much features.
1) check-if-cpu-temperature-information-is-available

wmic /namespace:\\root\WMI path MSAcpi_ThermalZoneTemperature get CurrentTemperature
//On Real PC
//CurrentTemperature
//3147

//On VM
//Node - Admin
//Error:
//Description not supported

Tested on vmware,virtualbox,windows server,app.any.run sandbox.

2) Win32_PortConnector

Get-WmiObject Win32_PortConnector
//On Vm it is null

//On real pc it looks something like that
Tag                         : Port Connector 0
ConnectorType               : {23, 3}
SerialNumber                :

PortType                    : 2
