Here is a one-liner that retrieves information about your operating system:
Get-WmiObject -Class Win32_OperatingSystem | Select-Object -Property *OS*
The result would look similar to this:
ForegroundApplicationBoost : 2 OSArchitecture : 64-bit OSLanguage : 1031 OSProductSuite : 256 OSType : 18
If you wonder what those numbers represent, go to an Internet search site of your choice, and search for Win32_OperatingSystem. One of the first links directs you to MSDN documentation.
And if you’d like to retrieve the information from a remote system, use the -ComputerName and –Credential parameters.
