Jeffrey Snover of Microsoft posted this script to provide a simple way to show WMI Classes within PowerShell.

Here is a script that I use to show WMI classes. I think you’ll find it useful. There is an example after the script:

##############################
# Show-WmiClass - Show WMI classes
# Author: Microsoft
# Version: 1.0
# NOTE: Notice that this is uses the verb SHOW vs GET. That is because it
# combines a Getter with a format. SHOW was added as a new “official
# verb to deal with just this case.
#############################
param(
$Name = “.”,
$NameSpace = “root\cimv2″,
[Switch]$Refresh=$false
)
# Getting a list of classes can be expensive and the list changes infrequently.
# This makes it a good candidate for caching.
$CacheDir = Join-path $env:Temp “WMIClasses”
$CacheFile = Join-Path $CacheDir ($Namespace.Replace(”\”,”-”) + “.csv”)
if (!(Test-Path $CacheDir))
{
$null = New-Item -Type Directory -Force $CacheDir
}
if (!(Test-Path $CacheFile) -Or $Refresh)
{
Get-WmiObject -List -Namespace:$Namespace |
Sort -Property Name |
Select -Property Name |
Export-csv -Path $CacheFile -Force
}
Import-csv -Path $CacheFile |
where {$_.Name -match $Name} |
Format-Wide -AutoSize
###### EOF ###########
