A simple powershell script to look up server hardware and OS information

This is a simple powershell script to query and display hardware and OS information from a remote computer.

It uses CIM (Common Information Model) that is available since Powershell version 3 so as long as you have version 3 and up, you should be able to run this script against any server that you have access to.

And if you are running powershell version lower than 3, you could simply replace "Get-CimInstance -ClassName" with "Get-WmiObject" in this script and  it should work without a hitch.

# Specify the server name here

$server         = "Server1"

# pull all the information
$hardware         = Get-CimInstance -ClassName Win32_ComputerSystem -ComputerName $server
$OS               = Get-CimInstance -ClassName Win32_OperatingSystem -ComputerName $server
$CPU              = Get-CimInstance -ClassName Win32_Processor -ComputerName $server
$PhysicalMemory   = Get-CimInstance -ClassName CIM_PhysicalMemory -ComputerName $server
$Bios             = Get-CimInstance -ClassName Win32_BIOS -ComputerName $server

# build custom array to get some key properties in a single row
$server_summary = New-Object PSObject
