WMI is a great and powerful technique: simply specify a WMI class name, and back you get all the instances of that class:
PS> Get-WmiObject -Class Win32_BIOS
SMBIOSBIOSVersion : 76CN27WW
Manufacturer : LENOVO
Name : 76CN27WW
SerialNumber : 1006250300406
Version : LENOVO - 1
How do you know the WMI classes, though? Here is a search tool:
function Find-WMIClass { param ( [Parameter(Mandatory=$true)] $SearchTerm = 'Resolution' ) Get-WmiObject -Class * -List | Where-Object { $_.Properties.Count -ge 3 } | Where-Object { $_.Name -notlike 'Win32_Perf*' } | Where-Object { $ListOfNames = $_.Properties | Select-Object -ExpandProperty Name ($ListOfNames -like "*$SearchTerm*") -ne $null } | Sort-Object -Property Name }
Simply specify a search term you are after. The code will find all WMI classes that contain a property with the search term in its name (use wildcards to widen the search).
This will find all relevant WMI classes that have a property that ends with “resolution”:
PS> Find-WMIClass -SearchTerm *resolution
NameSpace: ROOT\cimv2

Next, pick a class name and look at the actual data:
PS> Get-WmiObject -Class CIM_CacheMemory | Select-Object -Property *
