get-wmiobject
We can use the Get-WmiObject cmdlet to find information about the operating system. This cmdlet can be used to get instances of WMI classes or information about available WMI classes. There are a variety of ways to find the version and build number of our system. We can easily obtain this information using the win32_OperatingSystem class, which shows that we are on a Windows 10 host, build number 19041.
Some other useful classes that can be used with Get-WmiObject are Win32_Process to get a process listing, Win32_Service to get a listing of services, and Win32_Bios to get Basic Input/Output System (BIOS) information. The BIOS is firmware installed on a computer’s motherboard that controls the computer’s essential functions, such as power management, input/output interfaces, and system configuration. We can use the ComputerName parameter to get information about remote computers. Get-WmiObject can be used to start and stop services on local and remote computers, and more. Further information about the cmdlet can be found here and here.
